Three-port nonreciprocal circuit device, composite electronic component, and communication apparatus

Abstract

A center-electrode assembly (13) has a configuration in which center electrodes (21) to (23) are arranged, in an electrically insulated state, at the upper surface of a circular-plate microwave ferrite (20). The center electrode (21) is constituted by a first line conductor (21a) and a second line conductor (21b) which are arranged parallel to each other. The hot ends of the first line conductor (21a) and the second line conductor (21b) have connection portions (27) and (26), respectively, and the cold ends are connected to a ground electrode (25). The first and second line conductors (21a) and (21b) are arranged such that the hot end of the first line conductor (21a) and the cold end of the second line conductor (21b) oppose each other and the cold end of the first line conductor (21a) and the hot end of the second line conductor (21b) oppose each other to cause electromagnetic coupling.
