Single Channel Compact Power Amplifier (CPA)

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

  • Small size, weight and power
  • Addresses airborne and ground platforms
    • Rotary/fixed wing
    • Man pack—pull and jerk radios
  • Configurable waveforms/frequency band for SRW, WNW, SINCGARS, ANW2 (i.e. SRW/SINCGARS in one package)
  • Capable of simultaneous operation with additional CPA
  • 30-88 MHz and 225-450 MHz @ 25 W, 1250-1850 MHz @ 15 W, higher RF power outputs achievable
  • DC input from 10-36 V, 55 W nominal power consumption
  • No radio interface necessary, SPI available
  • Cosite mitigation for adjacent channels
  • Small form factor: 7.7″L x 1.2″W x 3.2″H w/connectors, 2 lbs.
  • Input frequency sensing
  • Automatic Leveling Control (ALC)
  • VSWR sensing
  • Environmentally sealed design
