Abstract
A microwave amplifier includes input-side and output-side matching circuits disposed on the input side and output side of a microwave FET. Each of the matching circuits is a distributed constant circuit including microstrip lines disposed on a substrate of dielectric material. The input-side matching circuit includes a connecting section for connection to the FET. The connecting section comprises a first microstrip line having a first width equal to that of the input-side matching circuit, and a second microstrip line continuous and integral with the first microstrip line and having a second width smaller than the first width. The connecting section connects the input-side matching circuit to the input of the FET.
