HIGH FREQUENCY CIRCUIT ELEMENT AND HIGH FREQUENCY CIRCUIT MODULE

摘要

A high frequency circuit element comprising a dielectric member (1), a shielding conductor (2) surrounding the dielectric member (1), support member (3) for fixing/supporting the dielectric member (1), and a pair of transmission lines (4) consisting of micro-strip lines. A transmission line (4) comprises a substrate (6) consisting of a dielectric, a strip conductor (5) and a grounding conductor layer (9). The tip end of the strip conductor (5) faces a part of the dielectric member (1) to function as a coupling probe for output coupling or input coupling. The transmission line (4) includes a strip line, micro-strip line, and a coplanar line, and suffers little loss when connected to a circuit board.
