Abstract
The switch circuitincludes a common terminal(common port), a plurality of branch terminals, a common path Pconnecting the common terminaland a diverging point N, branch paths P, Pconnecting the diverging point N and the branch terminalsrespectively, distributed constant FETsrespectively provided in the branch paths P, P, and transmission linesprovided between the diverging point N on the branch paths P, Pand the distributed constant FETsrespectively. Here, the transmission linesare longer than 45% of Λ/4 but shorter than Λ/4, when Λ designates a propagation wavelength under an operating frequency.
