90KW C Band, Liquid Cooled Hot Swappable SSPA

Empower’s Model 2225 is a long duty cycle pulsed amplifier operating from 5.2 to 5.9GHz and represents our new technologically advanced liquid cooled and scalable architecture. This breakthrough solid state GaN design replaces tube technology to bring new capabilities to EW, Radar, Directed Energy and Satcom applications where tens and hundreds of kilowatts of CW and Pulse power are required. This new modern architecture offers scalability for affordable upgrade paths to future power needs by adding hardware to an existing system. Additional racks can be combined and for racks not fully populated, 2U amplifier drawers can be added without the need for tuning.

The amplifier system layout consists of a system controller in a 3U and up to 16 hot swappable 2U amplifier drawers with each amplifier drawer containing an integrated power supply in its 2U chassis. This arrangement eliminates the risk of an RF section or single power supply failure taking the entire amplifier offline. In the event of a failure only a fractional reduction of output power is realized and the amplifier system remains on air.

Product Highlights
