Liquid-Cooled SSPA for Satcom Uplinks

Engineered for demanding satcom uplink applications, the Empower RF Model 2253 solid state power amplifier (SSPA), combines solid-state technology with a modular, liquid-cooled architecture. Operating from 1750 to 2120 MHz, the 2253 provides a 7 kW peak and 3.5 kW RMS of digitally-modulated output power. The 2253 is the latest member of Empower’s standard liquid-cooled SSPAs built for critical applications requiring solid-state power and high availability.

The 2253 system comprises a 6 ft. rack, eight 2U amplifier drawers, a built-in cooling distribution unit (CDU) and an external heat exchanger.
The architecture of the 2253 is distributed and modular, the latter allowing field replacement of amplifier drawers, the controller and CDU. The distributed RF and power supply design eliminates single points of RF failure, delivering “always on air” operation and minimizing downtime. The distributed system design provides system redundancies, allowing continuous amplifier operation at maximum potential in the event of partial failures. Similar to N+1 configuration redundancy, the 2253 offers impressive effective mean time between failures.
