Abstract

A nonreciprocal circuit element having low insertion loss is provided. In the circuit element, three central conductors are disposed such that they intersect each other at specified angles in an electrically isolated condition and a DC bias magnetic field is applied to the intersection. The intersection angles formed by the central conductors are set to different values, corresponding to the rotation angle of the high-frequency magnetic field caused by the DC bias magnetic field. A stronger operating DC magnetic field than that in a conventional circuit element is used to reduce a ferrite loss.
