VHF/UHF Compact Power Amplifier (CPA)

Product Description

Crescend Technologies Defense Solutions Products

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.

Performance Advantages

  • Small size, weight and power
  • Addresses airborne and ground platforms
    • Rotary/fixed wing
    • Man pack—pull and jerk radios
  • Capable of simultaneous operation with additional CPA
  • 30-512 MHz operation in transmit
  • Two selectable receive modes: LOS 30-512 MHz, SATCOM 240-320 MHz
  • DC input from 18-36 VDC, 75 W nominal power consumption in transmit
  • Input frequency sensing, no need for radio interface, SPI available
  • Cosite mitigation for adjacent channels, harmonic filters
  • Small form factor: 7.4″L x 2.4″W x 4.2″H w/connectors
  • Automatic Leveling Control (ALC)
  • VSWR sensing
  • Input to Output Bypass mode—normally closed when unpowered
  • All connections accessible on one panel, separate SATCOM antenna port
  • Environmentally sealed design
  • Fault detection and visual indicators
  • NSL, ESD and HEMP survivability per MIL-STD-464
