Abstract

A nonreciprocal circuit element according to the present invention comprises a nonreciprocal unit provided with a ferrite, an electromagnet that applies a DC magnetic field to the ferrite, and conductors that are arranged so as to intersect with each other in an insulated state with respect to the ferrite and that have a plurality of shorted terminal ends. The nonreciprocal circuit element comprises reciprocal circuit units and a DC power supply control unit controlling DC current to be supplied to the electromagnet. The DC power supply control unit controls the DC current to be supplied to the electromagnet and controls a DC magnetic field to be applied to the electromagnet. By the control of the DC magnetic field, the center frequency of frequency characteristics of the nonreciprocal circuit element is matched with the frequency of a high-frequency signal, and insertion loss of the nonreciprocal circuit element is reduced.
