250 W, 2 - 32 MHz, RF Amplifier, 19" Rack Mount
Download Full Data Sheet
The Model KAA3020 is a Class AB wideband RF power amplifier delivering in excess of 250 W CW power into a 50-Ohm load over the frequency range of 2 MHz to 32 MHz. Power gain is a minimum of 54 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 Model KAA3020 is a 19-inch rack-mount unit, 7 inches high and 20 inches deep. Construction is completely modular; all subassemblies are readily removable. Forced-air cooling is by a highly reliable, tube-axial fan mounted on the rear panel. The amplifier operates from 95-132 or 187-265 VAC, 47-63 Hz line. The system may be placed in 'stand-by' mode with the BLANKING switch, which greatly reduces energy consumption and heat generation.
