ABSTRACT:
A microwave amplifier circuit includes an amplifier having a gate to which a microwave signal is input and an output terminal from which an amplified signal is output, and a gate bias resistor having a variable resistance connected between the gate of the amplifier and a gate bias terminal for controlling a voltage applied to the gate while maintaining a constant bias voltage at the gate. Even when variations occur in the threshold voltage of the amplifier because of process variations, the gain of the circuit can be held constant, without the bias voltage being adjusted, so that yield is improved.
