ABSTRACT:
A high-frequency circuit device includes a dielectric member1, a shielding conductor2surrounding the dielectric member1, a support member3for fixing and supporting the dielectric member1, and a pair of transmission lines4each of which is formed of a microstrip-line. Each of the transmission lines includes a substrate6formed of a dielectric material, a strip conductor5, and an earth conductor layer9. An end portion of the strip conductor5faces part of the dielectric member1and functions as a coupling probe for input/output coupling. Each of the transmission lines4is formed of a strip line, a mictostrip line, a coplanar line or the like, and has low-loss when connected to a circuit board.
