The Amplifier Research Model KAW1020 is a general-purpose, wideband RF power amplifier for signals in the 500 kHz to 1000 MHz frequency range. No tuning, band switching, or adjustments of any kind are required to operate this unit. Power output is in excess of 5 Watts into a 50-Ohm load. Power gain is a minimum 36 dB making the amplifier compatible with drive power levels provided by most commercially available signal generatorsProtection 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.
