Multi-Channel VHF/UHF/L-Band Power Amplifier

The Crescend Technologies Multi-Channel High Power Amplifier is a small, lightweight (<10 lbs.) amplifier fully capable of extending the communication range for legacy and next generation waveforms. The combination of two internal frequency channels (UHF, VHF/L-Band) provide for Single Channel Ground and Airborne Radio Systems (SINCGARS) with flexibility supporting TrellisWare’s TSM Waveform, DAMA SATCOM and the Multiple User Objective System Waveform. The compact design is an ideal choice for airborne applications and compliant to MIL STD 704E.

Performance Advantages

  • Compact size, weight and power
