AR Modular RF in Bothell, Wash., is introducing a 50-watt auto-tuning, multi-band tactical RF amplifier to help soldiers maintain constant, reliable military radio communications in demanding environments. The AR-50 booster amplifier strengthens radio communications signals from handheld and manpack military radio systems operating in the 30-to-512 MHz band. The RF power amplifier provides 50 watts output for tactical radio with as little as 2 watts input and offers two antenna ports dedicated to line-of-sight (LOS) or UHF Satellite (SATCOM). The system also provides a switchable low-noise amplifier (LNA) and a three-position RF output level control. The small, compact, lightweight unit can run from either 12- or 24-volt vehicle power systems. For more information, visit AR Modular RF online at www.ar-worldwide.com.
