RF Booster Amplifier -- AR-75


The Model AR-75 is a portable, lightweight, fully automatic band-switching RF booster amplifier for multi-band VHF/UHF Tactical Radio equipment employing legacy, proprietary and emerging waveforms. The amplifier covers the frequency band of 30-512 MHz using automatically switched filters to assure low harmonic distortion levels and is SINCGARS, HAVE QUICK and ECCM compatible. The AR-75 is designed for operation from 18 to 32 Volts. The amplifier includes Voltage Spike Suppression for vehicle applications, RF sensing, T/R switching, Automatic Level Control (ALC), six automatically switched harmonic filter bands, and protection against antenna mismatch and over-temperature. Protection against accidental polarity reversal is provided. Optional cables and vehicle shock mounting kit are available.
