AR Modular RF is the leading supplier of booster amplifiers for tactical military radios, with a full line of amplifiers that cover the broadest frequency and wave forms. Each amplifier incorporates RF sensing circuits to switch from Receive to Transmit. They all include Automatic Level Control, appropriate low pass harmonic or band pass filters, and protection against antenna mismatch (VSWR) and overheating. Several models have fully automatic band selection and are SINCGARS-compatible with high speed filter switching to protect other nearby communication networks; and they are fully compatible and manufacturer independent with most radio transceiver systems operating in the frequency range 30 – 512 MHz.
