Safety Considerations

Potential safety hazards exist unless proper precautions are observed when workingwith this unit. To ensure safe operation, the user must follow the information, cautions,

and warnings provided in this manual as well as the warning labels placed on the unititself.

High Voltage Hazards

Only qualified service personnel should service the internal electronic circuitry of theCompact Outdoor Amplifier. High DC voltages (300 VDC) are present in the powersupply section of the amplifier. Care must be taken when working with devices that op-erate at this high voltage levels. It is recommended to never work on the unit or supplyprime AC power to the unit while the cover is removed.

RF Transmission Hazards

RF transmissions at high power levels may cause eyesight damage and skin burns.Prolonged exposure to high levels of RF energy has been linked to a variety of healthissues. Please use the following precautions with high levels of RF power.

Always terminate the RF input and output connector prior to applying prime ACinput power.

Never look directly into the RF output waveguide

Maintain a suitable distance from the source of the transmission such that thepower density is below recommended guidelines in ANSI/IEEE C95.1. The powerdensity specified in ANSI/IEEE C95.1-1992 is 10 mW/cm2. These requirements ad-here to OSHA Standard 1910.97.

When a safe distance is not practical, RF shielding should be used to achieve therecommended power density levels.

Phone: 1 (814) 238-3450Fax: 1 (814) 238-3829

Prime Power Connection

The Prime power connector is a 3-pin circular connector, J7. The power suppliesprovide universal AC input by using auto-sensing power supplies. The AC input canoperate over a range of 90-265 VAC, at 47 to 63 Hz. The power supply is also powerfactor corrected, enabling the unit to achieve a power factor greater than 0.93.

The highest output power levels, >70 W @ Ku-Band and >100 W @ C-Band should bepowered only from a 180265 VAC source. This will keep AC line currents to safeoperating levels for the internal EMI filter and associated circuitry. The AC Line inputconnector configuration is given in Table 2-1. The prime power vs. RF output power issummarized in Table 2-2. An option for 110 VAC prime power is available for thehigher-powered units.

AC Input (J7)

The AC Input connector, J7, is located on the bottom side of the Compact OutdoorAmplifier package. There are also two alternate placements for this connector on the

RF Output end of the amplifier as shown in Figure 2-4. This connector is a 3-pincircular connector, MS3102E20-3P. The mating connector (MS3106E20-3S) is shippedwith the unit. The pin out for this connector is given in Table 2-1.

Air flow

The air intake and exhaust are both located on the bottom side of the amplifier. Theintake is brought through two fans while the exhaust is along the two rows of heat sinkfins as seen in Figure 2-4. A minimum clearance of 6 inches (152 mm) should bemaintained between the bottom of the amplifier and any mounting surface. This willensure that there is no forced re-circulation of airflow from exhaust to intake. TheCompact Outdoor SSPA should NEVER be mounted with the fans facing up.

Doing so could void your warranty.

RF Output (J2)

The RF Output is brought out through waveguide in the Compact Outdoor Amplifier.Figure 2-4 shows the output of a C-Band Compact Outdoor Amplifier. The Ku-Bandamplifiers have a WR-75 Grooved Flange while the C-Band and X-Band amplifiershave CPR style grooved flanges (CPR-137G for C-Band; CPR-112G for X-Band). Anisolator is provided at the output flange with a termination capable of handling fullreflected output power.

Fiber-Optic Option

The Compact Outdoor Solid-State Power Amplifier is available with an integral fiber-optic interface or an external conversion box. Either configuration requires the addition

of a 1RU RCPF-1000 Fiber Optic Control Panel.

The RCPF-1000 Fiber Optic Controller provides easy remote monitor and control of theCompact Outdoor SSPA with integral or external fiber-optic interface. Control of theRCPF-1000 can be handled through front panel operation or remotely via parallel orserial communication to a remote computer running Paradise Datacoms UniversalM&C software.

The RCPF-1000 front panel includes 10 LEDs that indicate the internal state of theCompact Outdoor SSPA. Five fault condition LEDs on the left side of the front panelindicate any SSPA major faults, in addition to a summary fault state.

A 2 line by 40 character LCD provides an extremely user friendly interface. Virtually allof the controllers setup and adjustments are accessible from the LCD. Four navigationbuttons and a separate Enter key allow the user to navigate the firmware menu on theLCD. Separate buttons have been provided for frequently used functions. A range ofRF hardware options is offered to meet specific system requirements.

The rear panel features ports for Serial Main (J4), Serial Local (J5) and Parallel I/Oconnections, as well as N-type connectors for L-Band Tx and Rx paths, and FC/APCconnectors for Fiber Tx and Rx paths.

A complete description of the operation of the RCPF-1000 Fiber Optics Controller can

be found in its operations manual, Paradise Datacom document number 204640.

Introduction

This section of the manual describes the operation of the Compact Outdoor Solid StatePower Amplifier. The Compact Outdoor unit has been designed for maximum flexibility

in amplifier system configuration. It has a full compliment of parallel I/O monitor andcontrol signals as well as serial I/O capability using a PC and host communicationsoftware from Paradise Datacom LLC. Table 3-1 shows the pin out of the Monitor andControl connector, J4.

RF Input (J1)

The RF Input signal is applied to J1. The Compact Outdoor SSPA has a defaultmaximum nominal gain of 75 dB minimum. Therefore the maximum input signalrequired to saturate the amplifier can be calculated as:

Input Power = Psat 75 dB

For example, if a 50 W Ku Band Compact Outdoor amplifier is used in a system it hasa Psat= 47.0 dBm. Therefore the maximum input power should be limited to -28 dBm.Higher input power levels will not damage the amplifier but will result in higher levels ofdistortion in the output signal.

The maximum input level should be limited to +15 dBm to avoid damaging theamplifier.

RF Output (J2)

The amplifiers output is taken from the waveguide port, J2. Caution should beobserved here to make sure that the antenna or a suitable termination is connected tothis port before operating the amplifier. The amplifier is protected against full reflectionbut dangerous levels of microwave energy can be present at this port.

Never look directly into the RF output waveguide.

Amplifier Enable (Mute/Unmute) (J4)

The Compact Outdoor Amplifier has no on/off switch or circuit breaker in the AC Input

path. As soon as AC power is applied to J7, the units power supplies andmicrocontroller are enabled. The operator will be able to observe the forced convectioncooling fans running. However, the internal amplifier module is disabled until the MuteLine Input (J4 Pin B) is pulled to Ground (J4 Pin V).

If it is desired to have the RF enabled every time the AC input is applied, a permanentconnection can be made from J4-Pin B and Pin V.

Alarms (J4)

A variety of alarm signals are present at the M&C connector, J4. Both Form-C relaysand open collector outputs are available. An amplifier summary alarm is available in

both Form C relay and open collector output. Detailed internal faults are available inopen collector form and include: voltage, current, and over-temperature.

Summary Alarm (J4) Form C Contacts

The Summary Alarm is accessible in both Form C relay and open collector format.The form C relay is energized under normal operating conditions and deenergizedwhen a fault condition exists.

Auxi liary Alarm (J4) Form C Contacts

The Auxiliary Alarm relay is an end user alarm that can be used to signal an alarmcondition that is dependent on the state of the Auxiliary Input (J4-Pin P).

The Auxiliary Input is a contact closure to ground. When this input is pulled to groundthe Auxiliary Alarm relay is energized (Normal State). When the Auxiliary Input is opencircuited the Auxiliary Alarm relay is de-energized (Alarm State).

One example usage of the Auxiliary Alarm is that it could be used to signal one of thedetail alarms (voltage, current, or temperature) by connecting the appropriate opencollector alarm output to the Auxiliary Input. This programs the Auxiliary Alarm relay tobe either a voltage, current, or temperatue Form C relay alarm.

Open Collector Alarm Outputs (J4)

The open collector alarm outputs will require external pull-up resistors (unlessconnected to the Auxiliary Input). They are capable of sinking up to 20mA current at30 vdc. The open collector outputs are pulled to ground under normal operatingconditions and switch to high impedance state during an alarm condition.

Summary Alarm:high on any fault condition: voltage,current, or temperatureAuxi liary Alarm : follows state of Auxiliary Input as described aboveVoltage Alarm: high when amplifiers internal regulator voltage falls below itsacceptable level

Current Alarm: high when the amplifiers operating current falls below itsacceptable levelTemperature Alarm: high when the amplifiers baseplate temperature risesabove its acceptable threshold of 90oC. A 5oC hysteresis window exists in thetemperature alarm.Block Up Converter Alarm: high when the phase locked local oscillators lockalarm is triggered

RF Power Detector (J4)

The RF Power Detector is an analog output voltage that is proportional to the RFoutput power. The maximum output voltage is 4.0 vdc which corresponds to the

maximum (saturated) output power from the amplifier. This detected voltage is usefulover a 20 dB range of output power.

RF Output Sample (J3)

An RF sample of the amplifiers output is available at J3. This is a -40dBc coupledsample of the amplifiers output signal.

Gain Adjust Input (J4)

The Gain Adjust Input allows an analog voltage that is applied between (J4 Pin A)

and Ground (J4 Pin V) to control the gain of the amplifier. The gain is adjustable overa 20 dB range with 0.1 dB resolution. The applied voltage is directly proportional toamplifier gain.

2.5 vdc = Maximum Gain : 75 dB0.5 vdc = Minimum Gain : 55 dB

The Compact Outdoor SSPA is factory default to have maximum gain with no analoggain adjust. The gain adjustment must be enabled by running the setup program froma host PC. This prohibits any accidental gain adjustments that may occur fromunintentional analog voltages that may be present on the Gain Adjust Control J4-Pin A.

The gain is also adjustable using a host PC and the supplied Paradise DatacomControl program. See the Serial I/O Section for details on Serial Control.

Serial I/O Control (J4)

For serial data control of the Compact Outdoor SSPA, a Windows based M&C programis supplied with the amplifier that allows all of the control and alarm functionality over aserial communication link.

Both RS232 and RS485 can be used to communicate with the amplifier. The Amplifier

default is to operate on RS485 but can easily be set to RS232 by pulling the RS232/RS485 Select line low. This is done by connecting J4-Pin D to J4-Pin V.

Communication Links using RS232 are typically good up to 30 ft. (9 m) in length.Installations exceeding this length can use the RS485 mode which will allow serialcontrol up to 4000 ft. (1200 m).

Alarms Display

The Alarms frame in the lower right hand side contains eight fault lights thatcorrespond to :

Summary Temperature (SSPA module baseplate temperature)

Current (SSPA Module current)

Voltage Fault (SSPA internal voltage regulator)

External Mute (Alerts user that SSPA has been muted)

BUC Fault (Optional Block Up Converter fault)

Auxiliary Fault

RF SwitchThe Current and Voltage Regulator Faults are factory preset to alarm if the SSPAmodule current falls below 80% of its nominal value. The Temperature Fault indicatoris factory preset to alarm at 80oC. The amplifier will continue to operate up to 90oC.

Beyond 90o

C the DC power will be interrupted to the SSPA module. This measure willprotect the sensitive microwave transistors from catastrophic failure. The fans andmonitor and control circuitry will continue to operate normally. This function hasapproximately a 5oC hysteresis window which will allow the amplifier to re-enable itselfwhen the ambient temperature is reduced by 5oC. The Temperature Alarm is intendedto warn the operator of possible fan problems and eventual amplifier shutdown.

The BUC fault is only active in units that are supplied with an optional L-Band Block UpConverter module. If the Up Converters phase locked local oscillator looses lock, anBUC alarm is set and the amplifier is muted so that spurious RF can not be transmittedto the satellite.

The External (Ext) Mute line gives an indication via the M&C screen that the SSPA hasbeen externally muted by J4-Pin B. This external mute alarm can be configured totrigger a summary alarm if desired. The factory default is to signal a External Mute faultbut no Summary Alarm.

The Summary Alarm is simply a logical OR of any of the alarm indicators. The RFSwitch Alarm is only active if a 1:1 Redundant System has been configured in the M&Cprogram. This is covered in Section 7, the Redundant System Concepts description.

All of the above alarms, with the exception of the RF Switch Alarm and External Mute,

are available as open collector outputs and Form C relays on the J4 parallel interface.

Temperature Display

There is a thermometer display with a digital read-out positioned above that reports thepresent baseplate temperature of the amplifier. The baseplate temperature typicallyexperiences a 20 to 30 degree rise above ambient on the highest power CompactOutdoor Amplifiers and 15 to 20 degree rise on lower power units.

Gain Adjustment

The upper right hand side of the display has the Gain Adjustment Control. The gaincan be adjusted by setting the Attenuation Control. An Attenuation Control of 0 dB isthe maximum gain (75 dB) setting on the amplifier. By setting the Attenuation Controlto 20 dB; the gain is set to (55 dB). The Attenuation Control can be varied using thecontrol knob or the forward/reverse buttons.

Note the illuminated PC Control button inside the Attenuation Control frame. Thiscontrol lets the gain adjustment function be assigned to the analog input voltage (J4-Pin A). The gain adjustment control must be either under PC control or analog voltagecontrol; it cannot be both.

Indicators

The central area of the Operation window contains several indicators that displayvarious operating conditions of the Compact Outdoor Amplifier in real time. Theseindicators are helpful for any diagnostic proceedures. Among the horizontal indicatorsinclude:

Gate Voltage

Power Supply Voltage

Regulator Voltage

SSPA Current

The Gate Voltage indicator monitors the DC voltage of the gate circuitry of the

microwave GaAs transistors. The Power Supply voltage monitors the primary 12 voltpower supply output. Regulator Voltage is the DC voltage of the drain circuitry thatfeeds the GaAs transistors. SSPA Current is the total current drawn by the microwavetransistors. These indicators provide direct access to the active device operatingcharacteristics.

RF Power Indicator

The RF Power indicator is the vertical meter in the central part of the Operationwindow. This indicator reports the approximate output power of the amplifier. It usesthe voltage from the RF Power Detector to determine a corresponding power level in

dBm.

The accuracy of the power indicator is +/- 1 dB at the mid-point of the specified band,with a single CW or QPSK carrier.

This button is strictly an indicator which shows which computer COM port is connectedto the amplifier.

On Line Status

This button is primarily used when the amplifier is part of a Redundant System. Itswitches between On Line and Standby to indicate which path this particular amplifieris taking within a Redundant System. Pressing this button in a single thread amplifierwill simply refresh the screen.

Mute On/Off

This button toggles the amplifier between the Mute On and Mute Off states. When in

the Mute On (muted) state, the DC power that feeds the amplifier module is disabled.Notice that the current and regulator voltage both fall to zero when the amplifier ismuted. Voltage and current alarms will not be generated when the amplifier is mutedby software control. However an external hardware mute will generate a summaryalarm as this line is shared with the Block up converter alarm line. If the optional BlockUp Converter generates an alarm, the amplifier module is automatically muted so thatspurious signal power is not transmitted.

Operation Mode

This button is simply an indicator showing whether this particular amplifier is part of a

Redundant System or operating single thread or Stand Alone Mode.

Introduction

This section contains information on the theory of operation of the Compact OutdoorSolid State Power Amplifier. This includes a discussion of the system block diagram,amplifier module operation, and unique cooling system.

The Compact Outdoor Solid State Amplifier has been designed to be an extremelyrobust microwave amplifier system. It is very well suited for environmentally demandingconditions where reliability is paramount. At the heart of the amplifier system is amultifunction solid state power amplifier (SSPA) module.

Proprietary thermal management techniques allow even the highest output power levelamplifiers to operate reliably in environments up to 60o C ambient temperature and100% relative humidity.

Figure 4-1 shows the block diagram of the amplifier system. As seen in the blockdiagram there are five major active components:

AC / DC Converter

The prime AC input power is delivered to a switching converter module that produces300 VDC. This module is an auto-sensing, power factor corrected front end that has

proven reliability and allows the amplifier system to operate over a wide variety of inputpower conditions encountered around the world. A high current, common mode filter isused on the input side of the converter module that reduces switching components tovery minimal levels.

DC / DC Converter

The DC/DC converter module is also a switched mode power supply that converts the300 VDC to 12 VDC. This 12 VDC is the primary high current, DC voltage source thatoperates the entire amplifier system.

Solid State Power Amplifier Module

The amplifier module is a unique high density, multifunction module. It not only containsall of the RF signal amplification and distribution but is also home to the microcontrollerbased monitor and control circuitry. An extremely robust regulation and bias controlboard supplies the power to the microwave GaAs FET devices. A separatemicrocontroller board provides the M&C functions for the amplifier. Some of the featuresof this board include:

The Fan Boost Converter is a separate DC/DC boost converter that produces a 24VDC source from the 12 VDC output of the main power supply. This voltage source is

then used to power the two cooling system fans.

Cooling System

The Compact Outdoor Amplifiers cooling system represents a landmark in microwavetelecommunication amplifiers. It is a unique system of heatsinks that have beencomputer optimized to provide extremely efficient cooling of all of the systemsfunctional blocks. This high efficiency cooling system is primarily responsible for thesmall overall package size and reduced weight of the unit (approximately 36 lbs or 16.4kg).

The cooling system is based on a forced convection technique in which both systemfans provide the air intake while the exhaust is brought out around the outer perimeterof the fans. The fans are 150 CFM rated and operate into approximately 0.3 in. H20back pressure.

Introduction

This section describes some of the standard RF tests performed on productionamplifiers before shipment. Where possible Paradise Datacom, LLC maintainscomputer automated RF test stations to ensure a high level of accuracy andconsistency to production amplifier testing.

Gain and Gain Flatness

The amplifier gain is swept over the operating frequency range under small signalconditions to confirm the minimum gain and gain flatness specifications. The entireCompact Outdoor Amplifier is tested in a temperature chamber from -40oC to +55oC;and the gain is recorded.

P1dB

The 1 dB Gain Compression Point is measured at discrete frequencies across theband to characterize the output power over the operating frequency range. The P1dBisa guaranteed minimum specification.

Input and Output Return Loss

The input and output return loss are measured in all production amplifiers. This is ameasure of how closely the amplifier is matched to its characteristic impedance. Theinput impedance of the amplifier is a nominal 50 ohms while the output is matched tothe waveguide complex impedance.

Spurious

Spurious signals are undesirable byproducts of amplifiers caused by nonlinearitieswithin the amplifier and other system level components such as switch mode powersupplies. These unwanted signals cause signal management problems in systemapplications. Out of band spurious signals cause interference to other pieces ofequipment.

RF Sample Port

The RF Sample port is measured at discrete frequencies across the band and acalibration label is placed near the type N connector on the bottom of the unit. Thesample port is approximately -40 dB down from the RF output. A label with the exactcoupling ratio is attached to the amplifier chassis.

Intermodulation Distortion

Intermodulation distortion is one of the most important characteristics of a solid statepower amplifier system. Satellite communication systems must comply to certain

distortion levels depending on the service involved. All production amplifiers aresubjected to automated intermod testing. This is based on a standard two-toneintermod test in which the intermod level (IMD) is measured in dBc with respect themain tones and the highest third order intermod products.

Satcom amplifiers are typically used in some back-off condition. This is the operatingpoint at which the composite output power is backed-off from the amplifiers P1dB,compression point. A curve of back-off vs IMD level is especially useful in the selectionof a power amplifier or determining the proper output power setting in a Satcomsystem.

Paradise Datacom recognizes the importance of this back-off characteristic and

provides a plot of back-off Vs IMD from 1 dB to 10 dB back from the amplifierscompression point. Figure 5-1 shows a typical back-off curve from a production testset.

Introduction

This section describes some of the standard maintenance practices that can beperformed on the Compact Outdoor Amplifier.

Cooling System Maintenance

It is recommended that the cooling system be checked at least once per month. Thisinvolves visually inspecting the fan intakes to make sure that there is no obstructionsover the intake. The Windows-based M&C program can be used to check the amplifierbase plate temperature. The base plate temperature should normally not exceed a30oC to 35oC rise above the current outside ambient temperature. If the base platetemperature exceeds this temperature rise, it is one indicator that the systems airflowrequires maintenance.

The heat sink fins in the exhaust path can be visually inspected for excessive dirt anddebris buildup. If it appears there is excessive debris in the heat sink; the fan tray canbe removed for easy cleaning. Failure to keep the fans and heat sink clear ofdebris could void your warranty.

Fan Removal

It is recommended to remove prime AC power from the amplifier when the fan tray isbeing removed. However, if necessary, the fan tray can be removed while the amplifieris operating. Caution should be used to make sure that no clothing or fingers arecaught in the fan blades. Simply remove the four screws from the fan tray and the fan

assembly can be removed from the bottom of the amplifier assembly.

The fans are connected to their power source by weatherized in-line circularconnectors. A replacement fan with connector can be provided for replacement. Whilethe fan tray is removed, the heat sink fins can be cleaned by spraying compressed airthroughout the finned area. A can of dust remover spray such as that which is found ata computer or electronics shop will work fine.

7 Redundant System Operation

Redundant System Concepts

The Compact Outdoor Amplifier is capable of operating in a variety of redundantsystem configurations. These include 1:1 and 1:2 as well as 1:1 with L-Band Block UpConverters. The Compact Outdoor Amplifier has a built-in 1:1 redundancy controller,allowing it to be used in 1:1 redundant systems without a separate external controller.When used in a 1:2 redundant system a separate controller, RCP2-1200, is required.The three most common forms of 1:1 redundant system are shown in Figures 7-1through 7-3.

Figure 7-1 shows a standard 1:1 system in which the RF input is transmitted through atransfer switch along with the output. Using this configuration the standby amplifiercarries no traffic and simply is terminated by a 50 ohm resistive load at its input and bya waveguide termination at its output.

Figure 7-2: 1:1 Redundant System with input split ter substituted for input switch

With the system configured as in Figure 7-2, the RF input is passed through a micro-wave splitter. This keeps live traffic on the standby amplifier and is useful for observ-ing the traffic via the RF sample port on the standby amplifier.


46/140



The system shown in Figure 7-3 uses the same concept of the power splitter on the RFinput. In this case the Compact Outdoor amplifiers are equipped with L-Band block upconverters. L-Band input amplifiers use phase locked oscillators as the local oscillatorto the up converter. Such systems must use a splitter at the input instead of a switchso that the reference input is always available to the standby amplifier. If the referencesignal is lost the standby amplifier would report a BUC (Block Up Converter) fault.

Care must be taken when selecting the splitter for an L-Band input system. The splittermust be a wide band design capable of passing the 10 MHz or 50 MHz referencesignal along with the 950 MHz to 1525 MHz traffic input. The reference frequencypower level must be at least 10 dBm into each Compact Outdoor Amplifier.

Compact Outdoor Amplif ier in 1:1 Redundancy

The Compact Outdoor Amplifier is ideally suited for a self-contained and cost effective1:1 redundant system. Each Compact Outdoor Amplifier has a built-in 1:1 redundant

controller. The controller is activated via computer command from the ParadiseDatacom Universal M&C application. The Compact Outdoor Amplifier may bepurchased as a redundant system or upgraded in the field from a single threadamplifier to a 1:1 redundant system.

A redundancy kit may be purchased separately which includes the followingcomponents:

Hardware Setup

The hardware setup for a Compact Outdoor 1:1 Redundant System is very simple andinvolves the addition of (2) cables along with a redundancy switch. A schematicdiagram of the redundancy setup is shown in Figure 7-5.

The Link Cable is a simple (3) conductor crossover cable that allows the system topass command and control between amplifiers. With the redundancy kit, this cable issupplied in a 26 inch (660mm) length.

The Switch Cable is a Tee configuration and connects between each amplifier andthe redundancy switch. The Redundancy Switch is a 28 VDC type. Therefore thecontroller in each Compact Outdoor Amplifier is capable of supplying +28 VDC to thecommon voltage input. Either controller may then provide a (sink) return to engageeither position 1 or position 2 of the redundancy switch.

Care must be observed when connecting this cable to the amplifiers. The cable endlabeled A1 must be connected to the amplifier whose output is connected to Port 3 ofthe waveguide switch. Likewise the cable end labeled A2 must be connected to theamplifier whose output is connect
