50 Watts PEP, 30-512 MHz, Tx/Rx Booster Amplifer


AR Modular RF Model AR-50 is a portable, lightweight, RF sensing, band-switching, RF booster amplifier for multiband operation compatible with VHF/UHF/LOS/SATCOM tactical radio equipment supporting legacy, proprietary and emerging waveforms.  Operation covers 30 to 512 MHz using high speed auto-switching filters for harmonic suppression and is SINCGARS and HAVEQUICK compatible.  The amplifier is designed with a DC/DC converter to support a wide range of input voltages while not sacrificing output power.  Built in protections guard against antenna mismatch, over-temperature and accidental input power polarity reversal.  Built to last, the AR-50 is packaged in a rugged, IP67 rated, 2-piece aluminium enclosure.  Optional fan kit, shock mount kit and interface coaxial cables are available.
