WCDMA Bias-T descriptionThe Bias-T used in the Nokia Siemens Networks WCDMA Antenna Systems is an integral component of the WCDMA Masthead Amplifier (MHA). There are two versions of Bias-T available: Bias-T with VSWR (voltage standing-wave ratio) and non-VSWR Bias-T.Bias-T has two primary functions. It provides: Power to the Masthead Amplifier by injecting DC power into the RF feeder centre conductor, so separate DC cabling is not needed Fault monitoring of the antenna line VSWR (voltage standing-wave ratio) and Masthead Amplifier, forwarding alarm signals to the base station antenna filter unit (WAF)

The Bias-T transfers DC power via the antenna coaxial cable to the MHA connected to the antenna line. The Bias-T combines DC and RF energy onto the same coaxial cable and provides RF isolation toward the DC voltage supply and DC isolation towards the BTS. The BTS TX power is fed through the Bias-T.

The VSWR alarm function indicates that the antenna, MHA, feeders or jumpers have developed problems which impair their functioning. The Bias-T with VSWR can be installed to a WCDMA Antenna System without an MHA as a stand-alone unit to provide lightning protection and VSWR monitoring.

Flexi WCDMA BTS Internal Bias-T VSWR Tuning

Choosing the Antenna Tune VSWR Threshold menu item opens the Tune VSWR Threshold dialog box, where you can tune VSWR alarm threshold values for antenna filters inside RF modules.

The VSWR treshold tuning is used for defining values when an alarm notification needs to be sent for a minor problem of an antenna line condition (decreased condition) and for a major problem condition (cell blocking).

The VSWR threshold tuning can be also used (indirectly) to find out the actual VSWR value by changing the values and monitoring alarms.

Flexi WCDMA BTS Internal Bias-T VSWR Tuning

Check the antenna for which tuning of VSWR is required.Specify Minor and Major Ranges. (VSWR Values from 1.5 to 3.5)Start Tuning. The Alarms column shows the states of VSWR alarms for each filter. When the tuning mode is activated by clicking the Start Tuning button, sending alarms to the NetAct from the selected antenna lines is blocked. Alarms will not be sent until the tuning is stopped by clicking the Stop and Save or Stop without Saving button.

WMHC block diagram

WCDMA Dual MHA monitoring and alarmsIf the MHA unit fails, a bypass mode ensures that the antenna line sector continues operatingAlarms are sent to the BTS via the DC feeders so if the power to the MHA is switched off the alarms are switched offIf MHA power is lost, the MHA no longer amplifies the Rx signal, but the by-pass operation is still able to pass through the Rx path (with minor loss).The MHA has an operational current 'window' and providing the current consumed is within this window and within the specified DC voltage range, the MHA operates correctlyWhen the monitored MHA current consumption is outside this window, an MHA alarm is activatedThe BTS operating software confirms the alarms and performs a recovery action applicable to the version of BTS operating software being used

To identify the specific software recovery action, please refer to the BTS Software User Manual for information

An MHA alarm alerts if the MHA Low Noise Amplifier (LNA) is defective or outside the operational limits

NoteIf open or high impedance exists along the antenna line supplying the MHA DC supply, this indicates a VSWR alarm conditionIf an MHA alarm is activated, the cause of the alarm must be identifiedOnce the cause is clearly identified, the appropriate corrective actions can be performed to correct the fault

Tower Mounted Amplifier (TMA)

The Tower Mounted Amplifier (TMA) is a RF unit performing the following functions: Amplifying the uplink signal received from the TX/RX antenna

with a low noise figure. Feeding the overall Node B downlink signal to the TX/RX

antenna The TMA is an optional but highly recommended unit as it

compensates cable losses in the uplink and thus ensures lower noise disturbance.

High selectivity filters ensure high TX/RX separation, enabling the reception of low signal levels in the uplink. It therefore improves link quality and link availability at the cell borders

The TMA is always installed outside the Node B rack/shelter and close to the antenna, thus achieving fixed sensitivity independently of the feeder cable length.

TMA Variants 1/2

There are five variants of TMA:TMA The TMA is a two-port RF unit (1 x in, 1 x out) Two TMA modules are required for each sector to support the RX main path and

the RX diversity path

DTMA The DTMA (Dual Tower Mounted Amplifier) is a four-port RF unit (2 x in, 2 x out) Consists of two identical TMA submodules in a single housing One submodule is used for the RX main path and the other for the RX diversity

path One DTMA module is thus required for each sector The DTMA is very efficient in combination with a cross- polarized antenna

TMA Variants 2/2

TMARET The TMARET is a TMA module additionally providing an IF converter and the

RS485 interface in order to support control of a RET module

DTMARET The DTMARET is a DTMA module additionally providing an IF converter and the

RS485 interface in order to support control of a RET module

SDTMA The SDTMA (Single Feeder Controlled DTMA) has the same capabilities as the

DTMA module Additionally supports DC power supply and SDTMA signalling via one port for

both TMAs inside the SDTMA SDTMA is SW-prepared to switch from dual feeder controlled to single feeder

controlled DTMA if required in the current configuration In case of dual feeder control the RET functionality is provided

The RET (Remote Electrical Tilt) module is located directly under the antenna and contains a stepper motor which adjusts a phase shift within the antennaThis module is accessed from a RET capable TMA module (TMARET/DTMARET/SDTMA) via the RS485 interfaceRET specific commands enter the Node B at the Core Controller, are routed through a RET capable DUAMCO (variant DUAMCORET) and are transmitted to the RET module via the RET capable TMA moduleThe signals are sent over the HDLC protocolIn the opposite direction the RET module sends information and alarmsRET signaling and DC power from the DUAMCO to the TMA and vice versa is transported through the antenna feeder cable; a triplexer is integrated in the TMA to provide these functionsA special cable is needed between the TMA and the RET module for the RETs DC voltage and the RS485 interface

The TMA and its variants are powered by the related DUAMCOs (e.g. TMA/DTMA by DUAMCORT and TMARET/DTMARET by DUAMCORET).

Concept of TMA and DTMA

The TMA module consists ofone duplexer subsystema triplexera low-noise amplifier (LNA) with a fail-safe path and a bias & signaling board

The transmit path consists of the TX part of the duplex filtersThe receive path consists of the RX part of the duplex filters and contains the LNAThe triplexer combines the TX and the RX path with the TMA signaling path (e.g. alarms). Therefore only one feeder cable is required between the TMA and the Node BThe TMA is supplied with +12 V DC through the feeder cable from the Node B

The LNA within the TMA has two parallel gain elements:If a single failure occurs, operation continues with reduced gainIf both gain elements fail, or the supply of the TMA fails, the LNA is bypassed by a fail-safe switch.

The DTMA module consists oftwo RF portsa duplexer subsystema triplexeran LNA with a fail-safe path and a bias & signaling boardFor each sub-module, signaling and DC power supply are provided through the associated feeder cables from the Node B

Pole Mounted DTMAF

The hose clips surrounds the pole and are fitted into the corresponding openings of the mounting plate (see rear view of the devices). This is the situation just before tightening the hose clips.For the mounting, the following steps can be generally recommended. First connect the DTMAF / DTMARETF to the antenna feeder cable. Take into consideration that the antenna feeder often is very stiff and rather heavy. The position of its coaxial connectors therefore often determines the position of the DTMAF / DTMARETF on the pole.1. Place the DTMAF / DTMARETF in its final mounting position at the pole.2. Secure the unit with a tensioning belt.3. Open the hose clips by pressing the button at the end of the clip lock and then smoothly pull out the perforated metal band.4. Move the metal band of the hose clip gently into the openings of the mounting plate.5. Close the hose clip loosely around the pole.6. Tighten the hose clip screws carefully, but do not over-tighten.7. Remove the tensioning belt.8. Connect the DTMAF / DTMARETF first to the antenna feeder cable (NodeB) and then to the antenna jumper cable (ANT). The torque must be 25 Nm (18.5 ft lb).9. Connect the protective earthing conductor with the DTMAF / DTMARETF ground screw. Tighten the connection to a torque of 5 Nm (3.7 ft lb).10. The use of self-vulcanizing tape as an environmental protection of the connectors is recommended.

Pay attention to the thermal dimensional changes of the antenna feeder cables. If the antenna is equipped with a RET module, install the DC power / data cable between the module and the 8 pole circular connector of the DTMARETF. The required cable will be delivered with the RET module together.

WMHD WCDMA Dual MHA (RAS06)

WMHD MicroMHA comprises two identical amplifiers in one compact integrated package which is easy to transport and install. A state of the art Low Noise amplifier design provides a nominal 12 dB of gain, compensating feeder loss and improving coverage. In the unlikely event of component or power failure, a bypass path allows the BTS to continue operation.

Power is fed via the feeder cable, in Flexi BTS no BiasTs are needed, WMHD gets its power and control directly from BTS. With Ultrasite one BiasT is needed.

WMHD has also RET connector for remote antenna tilt adjustor, RTA.WMHD Mast Head Amplifier is upgrade on WMHC. WMHD adds RET output connector and AISG controlling to WMHC. Remote antenna tilt users saves RET bias-t and installing time.

RF-performance and outlook will remain same as WMHC.
