Patent number: 6310517Abstract: A microwave amplifier (10) of the present invention contains such an arrangement that both an inductor (12) and a resistor (13) are loaded in a parallel manner between a source electrode of a field-effect transistor (11) and the ground. Since the inductor (12) has a stray capacitance component (B), the inductor (12) is resonated at a resonant frequency “f0”. However, since the source electrode of the field-effect transistor (11) is grounded via a resistor (13) connected in parallel to the inductor (12), even when the inductor (12) is opened due to a resonant operation, the field-effect transistor (11) is operated under normal condition. As a result, the operation of the microwave amplifier (10) is stabilized.Type: GrantFiled: November 23, 1999Date of Patent: October 30, 2001Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Kazuhiko Nakahara, Yasushi Itoh
