Single Channel VUL Compact Power Amplifier (CPA)

Single Channel VUL Compact Power Amplifier (CPA)

Defense High-Reliability

Small, lightweight, and rugged power amplifiers are the benchmark and platform for Crescend’s VHF/UHF/L-Band 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.

Performance Advantages
