変調器。 It has a carrier wave input terminal and a control signal input terminal,
a modulator that modulates a carrier signal from the carrier wave input terminal; a power amplifier that amplifies the output signal of the modulator; a linear detector that branches a part of the output signal of the power amplifier and linearly detects it; and a differential amplifier that takes and amplifies the difference between the detected output signal of the detector and the AM modulation signal input from the outside, and supplies the output signal of the differential amplifier to the control signal input terminal of the modulator. Features high power AM
modulator.
