Nonreciprocal circuit element

摘要

A nonreciprocal circuit element having low insertion loss is povided. In the circuit element, three central conductors (2,3,4) are disposed such that they intersect each other at the 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, correspondingly 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 of conventional one is used to reduce a ferrite loss. <IMAGE>
