ABSTRACT:
In a two-port non-reciprocal circuit device, connecting portions of a first central electrode are electrically connected to first and second balanced input terminals, respectively. Likewise, connecting portions of a second central electrode are electrically connected to first and second balanced output terminals, respectively. First and second resistors are electrically connected between the first balanced input terminal and the first balanced output terminal and between the second balanced input terminal and the second balanced output terminal, respectively. First to fourth matching capacitors are electrically connected between the connecting portions of the first and second central electrodes and ground, respectively.
