The Amplifier Research Model KAW2080 is a Class A wideband RF power amplifier delivering in excess of 150 Watts CW power into a 50-Ohm load over the frequency range of 20 MHz to 1000 MHz. Power gain is a minimum of 52 dB. GPIB control requires the optional IEEE488.2/RS232 Interface Controller Module. The system features forward and reflected power indication on a front panel-mounted, analog meter; Automatic Level Control (ALC); RF gain control; overdrive protection; full VSWR protection; input blanking, and over-temperature protection. On the basic model these features, plus remote power on/off control, are accessible for hard-wire remote operation through a 25-pin, Dsubminiature connector. For a detailed description of these features refer to SPECIAL FEATURES KAA & KAW-SERIES SINGLE BAND RF POWER AMPLIFIERS.
