Abstract
PURPOSE: To eliminate parasitic reactance generated at a connection part between the input and output terminal of an FET and a balanced stip line, by connecting the grounding plate of the balanced strip line to the upper lid of a package by a metal.
CONSTITUTION: A metallic plate 14 connects the 2nd grounding plate 9 to the upper lid 2 of a package. A current I2 on te 2nd grounding plate 9 passes through the metallic plate 14 and upper lid 2 of the package to flow to a source lead wire 3. Thus, the current I2 flows in the propagation direction of the same radio wave with a current I1 on the grounding plate 8, so there is no parasitic reactance between the 2nd grounding plate 9 and the upper lid 2.
