Abstract

PURPOSE:To control the output of a power output tube to a constant value, by taking out the differential voltage between the detection voltage of a power detector and a reference voltage corresponding to the set output power by a differential amplifier, amplifying the differential voltage by a booster amplifier, and outputting it to the power output tube. CONSTITUTION:A differential amplifier 2 amplifies differentially a level signal proportional to the power obtained from a power detector 5 and an output set signal which is set by a potentiometer Rs for output setting, and the output is given to a booster amplifier 3. The amplifier 3 supplies a screen grid voltage Vg2 corresponding to the output voltage of the amplifier 2 to a tetrode V1. The tetrode V1 has a cathode currentIk changed by changing the voltage Vg2, and thus, the output is controlled.
