Abstract
A high-frequency circuit device includes a dielectric member, a shielding conductorsurrounding the dielectric member, a support memberfor fixing and supporting the dielectric member, and a pair of transmission lineseach of which is formed of a microstrip-line. Each of the transmission lines includes a substrateformed of a dielectric material, a strip conductor, and an earth conductor layer. An end portion of the strip conductorfaces part of the dielectric memberand functions as a coupling probe for input/output coupling. Each of the transmission linesis formed of a strip line, a mictostrip line, a coplanar line or the like, and has low-loss when connected to a circuit board.
