The Model KAW2200 is a Class AB wideband RF power amplifier system delivering in excess of 300 Watts CW power into a 50-Ohm load over the frequency range of 100 MHz to 500 MHz. Power gain is a minimum of 55 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, D-subminiature connector. For a detailed description of these features refer to “SPECIAL FEATURES – KAA & KAW-SERIES SINGLE BAND RF POWER AMPLIFIERS”. The system comprises an Amplifier Unit and a Power Controller/Supply Unit. The Model KAW2200 uses a switching-type power supply module and operates from 187-265 VAC, 47-63 Hz line. Power consumption is 1.8 kVA maximum. The system may be placed in 'stand-by' mode with the BLANKING switch
