The Model KAA2030M11 is a special-purpose, RF power amplifier at the frequency of 500 KHz. This product does not require tuning, band switching, or adjustments of any kind. Power output is in excess of 300 Watts into a 50-Ohm load.
Construction of the KAA2030M11 is in a 5¼-inch high cabinet, 16 inches deep, exclusive of handles, and 10.5 inches wide, with mounting flanges. Input and output connectors are located on the rear. Forced-air cooling is by a highly reliable, tube-axial fan mounted at the rear.
Protection against excessive heat rise of the amplifier module heatsink is by a temperature-sensing switch that interrupts the gate bias supply to the amplifier devices when activated. Operation resumes automatically when temperature has returned to normal operating temperature.
