Abstract
A microwave amplifier includes a field effect transistor having its source grounded. The drain of the transistor is connected through a first inductor of gold wires to an output-side matching circuit, while the gate of the transistor is connected through a second inductor of gold wires to an input-side matching circuit. A series circuit including a capacitor and a third inductor is disposed near the input-side matching circuit and is connected between the junction of the input-side matching circuit and the second inductor and a reference potential.
