Abstract
A lower-noise microwave amplifying circuit for use in a lower-noise converter includes a metallic conductor for use in performance adjustment. The metallic conductor projects from the microstrip line and is provided near a bendable connecting portion between an input coaxial rod in a coaxial waveguide conversion portion and a microstrip line for constructing one portion of an amplifying circuit. Therefore, the lower-noise microwave amplification circuit is easily adjusted for improving the basic characteristics such as input VSWR or the like and is simpler in construction.
