PowerMAX “Innovation in Modularity”

PowerMAX is the latest advancement in Modular SSPA Technology

•Systems can be configured in 4 module, 8 module, or 16 module systems.

•Systems configured with a variety of module power levels to custom fit your redundant power requirement.

•Systems are completely field scalable:•Start out with 4 modules. Grow system to 8 modules and/or 16 modules over time.•No need to return system to factory for upgrade.•Reduces initial equipment investment cost.

•All active components are modular and hot swappable from the front or rear panels including:

•Power Supply Modules•Fans•SSPA Modules•M&C Card

U.S. patent 8,189,338 B2

56

RF Soft-Fail Redundancy

� Modular Amplifiers should be sized such that a failure of 1 module can be tolerated by the system power budget. This is known as “n+1” redundancy.

� 4 Module System: loss of 1 module results in 2.4dB reduction in output power



� In all cases the system automatically adjusts its gain to maintain constant gain with the loss of one or more modules.

57

Efficient Power Combining

� Extremely efficient power combining is at the heart of the PowerMAX architecture.

� Advanced 3D Electromagnetic Modeling Techniques are employed to design near loss-less 4-way combiners.

� The easily assembled 4-way combiner makes it very convenient to add SSPA modules in groups of four.

� All Passive Combining & No Switching results in “hitless” operation.

58

Pure Parallel System Architecture

� System is designed to be “Purely Parallel” .

� Failure of a Chassis or M&C Card will have no impact on the system operation.

� Unlike some modular amplifiers, PowerMAX is fully redundant right down to the Monitor and Control functionality.

� The loss of a M&C card will not interrupt system remote control.

� System remote control is available as RS485 or Ethernet.

59

Simplicity of Operation� The sophisticated system monitor and

control allows the system to be operated as if it were a “single” chassis amplifier.

� Single chassis-like operation is maintained with remote control as well as local (front panel) operation.

� The system output power detection is measured in “True rms” watts or dBm. power meter accuracy.

� Most HPA systems today use diode (peak) power detectors that do not accurately measure multicarrier or modulated signals.

� PowerMAX reports the true aggregate output power regardless of the number of carriers and modulation schemes.
