The Model AR-20B is a portable, lightweight, fully automatic band-switching RF booster amplifier for use with multi-band VHF/UHF Tactical Radio equipment employing legacy, proprietary, and networking waveforms. The AR-20B produces 20 Watts from a 1 to 2 Watt PEP radio input and covers the frequency band of 30-512 MHz. The unit has a wide range of input DC voltage allowing operation from a single battery (XX90 battery) or 12 and 28 VDC vehicle power sources.
It also includes Over Temperature Protection, RF sensing, T/R Switching, Automatic Level Control (ALC), Harmonic Filters, Co-Site filters, and protection against antenna mismatch. The amplifier is comprised of a rugged 4-piece aluminum case. The AR-20B is the simpler version of the 20W family without an LNA and power select (contact AR Modular RF for the unit with the LNA feature). Optional interface coaxial cables, DC battery cables, and kits for man-packing the amplifier are available.
