C-Band Solid-State Troposcatter Amplifier
The ARMA-CL2500A is a C-band 2.5 kW GaN troposcatter power amplifier with redundant input/driver module, splitter panel, RF chassis with four 500 W amplifier modules, power supply module, and power combiner. Each amplifier module is adjusted for a normalized phase and gain and they are field-swappable with input and output connectors on the front and blind-mate connectors at the back. A microcontroller in each module specifies the timing specifications and has an RS485 interface. The amplifier modules report on fault conditions and internal temperature and a failed RF module can be removed and replaced by a spare without tuning and adjustment. A single failed RF amplifier will cause only a 1.16 dB drop in the total output power of the system.
