Abstract
A microwave amplifier includes an FET, a DC bias voltage supply circuit, and a beat smoothing circuit. The FET amplifies a microwave signal including a plurality of carrier frequencies that are different from each other. The DC bias voltage supply circuit supplies a DC bias voltage to the FET. The beat smoothing circuit removes a beat frequency generated on a line connected to the FET due to a difference among the plurality of carrier frequencies. The beat smoothing circuit is constituted by a microstrip line having a low impedance with respect to the beat frequency, and a capacitor for short-circuiting to ground the beat frequency output from the filter means.
