THICK-FILM HIGH FREQUENCY SIGNAL CIRCUIT APPARATUS WITH FEEDTHROUGH CAPACITOR

摘要

A thick-film high frequency signal circuit apparatus with a feedthrough capacitor. The apparatus includes a thick-film circuit (28a) in which a high frequency signal circuit is constituted on a substrate (33) in a thick-film configuration, a shielding case (27) for housing the thick-film circuit (28a) therein, a feedthrough capacitor (20a) constituted on one surface of the substrate (33) in the thick-film configuration and a terminal (50) for transmitting signals between the thick-film circuit (28a) and a circuit outside the shielding case (27), the terminal (50) having a first end (50a, 50b) coupled to the thick-film circuit (28a) through the feedthrough capacitor (20a) and a second end (50c) protruding outside the shielding case (27) through a hole (31) defined therein.
