Atec KAA1020 User Manual
MODEL KAA1020
25 WATTS CW
10 kHz - 230 MHz
The Model KAA1020 is a general-purpose, wideband RF power amplifier for signals in the 10 kHz to
230 MHz frequency range. No tuning, band switching, or adjustments of any kind are required to
operate this unit. Power output is in excess of 25 Watts into a 50-Ohm load. Power gain is a
minimum 43 dB making the amplifier compatible with drive power levels provided by most
commercially available signal generators.
The construction of these is in a 5¼ or 7-inch high cabinet, 14½ inches deep, exclusive of handles,
and 11½ inches wide. They are intended for bench-top use, but may be supplied with a rack
mounting kit installed. Input and output connectors are N-type female and are located on the front.
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.
