VHF/UHF Compact Power Amplifier (CPA)

Small, lightweight, and rugged power amplifiers are the benchmark and platform for Crescend’s VHF/UHF High Power Amplifiers (HPA).  The CPA supports tactical radio communication and datalink applications for clear, error free voice and data both on the ground and in the air to the warfighter.

The CPA is a small, lightweight (3lbs.) single channel amplifier that extends the communication range for legacy and next generation waveforms. The combination of VHF and UHF frequency channels provides capability to amplify Single Channel Ground and Airborne Radio Systems (SINCGARS), TSM, Havequick, Soldier Radio Waveform (SRW), IW SATCOM, AM, FM, FSK and PSK and P25. The small, lightweight design is an ideal choice for airborne, soldier carry, and ground vehicle applications.
