The Comtech PST 88258-30 is an 800 MHz to 2.5 GHz, 30 Watt RF Broadband Power Amplifier. The Comtech AR Series wireless amplifiers are rack-mountable units which incorporate the Series AM amplifier in a cabinet containing a built-in universal AC power supply (for models up to 100 watts).

Models are available for operation at frequencies from 800 to 3600 MHz and power from 10 to 300 watts. They are forced-air cooled by blowers built into the mechanical package. AR models are also available with an optional IEEE BUS for remote control and monitoring (ARD version).
