THREE-PORT IRREVERSIBLE CIRCUIT ELEMENT, COMPOSITE ELECTRONIC COMPONENT, AND COMMUNICATION DEVICE

摘要

A center electrode assembly (13) has center electrodes (21 to 23) arranged on a disk-shaped microwave ferrite member (20) and electrically insulated from one another. Each center electrode (21) is composed of first and second line conductors (21a, 21b) arranged parallel to each other. The line conductors (21a, 21b) have respective connection portions (27, 26) at their hot ends. Earth electrode (25) is connected to the cold end of each line conductor. The hot end of the first line conductor (21a) is opposed to the cold end of the second line conductor (21b). The cold end of the first line conductor (21a) is opposed to the hot end of the second line conductor (21b). Thus, electromagnetical coupling is established.
