ABSTRACT:
A non-reciprocal circuit device includes a yoke that is small-sized, has a simple structure, has sufficient adhesive strength, and can achieve favorable performance characteristics. The non-reciprocal circuit device includes a planar yoke, permanent magnets, a ferrite to which a DC magnetic field is applied by the permanent magnets, and first and second center electrodes located on the ferrite. The planar yoke is located on the upper surface of the ferrite-magnet assembly through an adhesive layer. On the rear surface of the yoke, protrusions are arranged in a lattice manner, and the protrusions increase the adhesive strength and facilitate the flow of a high-frequency field generated from the second center electrode.
