The Comtech PST CORP AR1929-30 is a professional-grade Class A linear solid-state power amplifier operating in the 1.9 to 2.9 GHz frequency range. Delivering a minimum of 30 Watts of power at 1dB compression, this rack-mountable amplifier is designed for general-purpose linear applications, incorporating built-in forced-air cooling and an integrated universal AC power supply. An IEEE-488 (GPIB) interface is optionally available for remote control and monitoring in the ARD configuration.
