Nonreciprocal circuit device

Abstract

A nonreciprocal circuit device reduces layout space when single-board capacitors are used, and meets demands for a smaller and lighter configuration. An isolator (nonreciprocal circuit device) comprises a ferrite, a permanent magnet applying a direct current magnetic field to the ferrite, a plurality of central electrodes respectively having ports disposed on the ferrite and a matching capacitor with capacitor electrodes formed on both surfaces of a dielectric substrate such that the capacitor electrodes are opposed to each other and sandwich the dielectric substrate, wherein the ferrite has a square shape and the capacitor electrodes of the matching capacitors are tilted at an angle of 60 to 90 degrees toward a mounting surface and the matching capacitors are disposed so as to surround sides of the ferrite.
