Abstract:
A microwave amplifier including: a bias circuit that includes a line having an electrical length of one quarter the wavelength at the frequency configured to be amplified by the microwave amplifier and being connected between the output terminal of an amplifier and a bias voltage source, and a capacitor connected between a terminal where the line is connected to the bias voltage source and a ground that defines the reference potential of the microwave amplifier; and a resonant circuit that includes a resistor and a capacitor connected in series between the ground and the terminal where the line is connected to the bias voltage source.
