摘要： The present invention provides a nonreciprocal circuit device which has solved problems, such as the increase in production cost, the reduction in reliability, and the overall upsizing thereof, which are caused by the mounting of a circuit element having a matching circuit onto a printed board, and also provides a communication apparatus including this nonreciprocal circuit. This nonreciprocal circuit includes a ferrite assembly formed by combining mutually intersecting first and second central conductors and a ferrite, magnets applying an magnetostatic field to this ferrite assembly, and a yoke. Furthermore, circuit elements which are connected to the first and second central conductors and which constitute a matching circuit, are formed in a dielectric laminated substrate, on which the ferrite assembly is mounted.

摘要： A nonreciprocal circuit device miniaturized entirely by reducing the height and the weight can prevent characteristic deterioration. In the nonreciprocal circuit device, a ferrite assembly is formed by winding a quadrangular ferrite plate with insulated copper wires mutually intersecting. The ferrite assembly is arranged perpendicularly to the mounting surface of a mounting substrate. On each side of the ferrite assembly, there is arranged a magnet applying a static magnetic field perpendicularly to main surface of the ferrite plate.

摘要： A highly reliable nonreciprocal circuit device facilitating incorporation of matching capacitors and a communication apparatus incorporating the same are disclosed. In the nonreciprocal circuit device, central conductors are integrally extended from a ground plate abutting on the bottom of a ferrite plate to be mutually crossed on the upper surface of the ferrite plate via an insulation sheet after passing over the side surfaces of the ferrite plate. Matching capacitors are connected by soldering between capacitor-connecting terminals integrally extended from the ground plate and the ports of the central conductors in such a manner that electrode surfaces of the matching capacitors are set perpendicularly with respect to a main surface of the ferrite plate.

A dielectric substrate is disposed in between the permanent magnet and the magnetic assembly. An inductor forming part of a &pgr;-type low-pass filter is provided as an example of a circuit element on the dielectric substrate, a dielectric layer or film being disposed between the dielectric substrate and the magnet.
