Abstract: A nonreciprocal circuit device attenuates unnecessary waves having a higher frequency than that of a fundamental wave, without increasing insertion loss. The nonreciprocal circuit device in the form of a 2-port type isolator includes a ferrite on which a first central electrode and a second central electrode are arranged to cross each other and so as to be electrically insulated from each other. A bypass circuit including a phase shifter and a filter is provided between an input port and an output port, and the bypass circuit does not allow signals in the fundamental wave band to pass through and also attenuates harmonics.

The second and third central electrodes have connecting portions at first ends thereof and the second ends thereof are connected to a ground electrode. The first central electrode has connecting portions at both ends thereof. The connecting portions of the first central electrode serve as feeding ends. An input port provided by the ends of the first central electrode serves as a balanced input port. An output port connected to the second central electrode serves as an unbalanced output port. Another port connected to the third central electrode serves as a terminating port.
