摘要： A nonreciprocal circuit device requires less 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 single-board 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. In various embodiments, the permanent magnet and/or the ferrite has a square shape and the capacitor electrodes of the matching capacitors are arranged at an angle of 60 to 90 degrees with respect to a mounting surface and the matching capacitors are disposed so as to surround the sides of the ferrite.

摘要： One or two inductor electrodes formed of hairpin-bent or curved electrode patterns are made on one main surface of a component member of a nonreciprocal circuit device, and connection electrodes are formed on the other main surface at positions corresponding to both ends of each inductor electrode. The component member may be a spacer member or a terminal board. Both ends of each inductor electrode are connected to the connection electrodes by through holes. The port sections of central conductors at the signal input and output side are connected to input and output terminal electrodes through the inductor electrodes, formed on the component member of the nonreciprocal circuit device. Each inductor electrode forms a low-pass filter in combination with capacitances in the nonreciprocal circuit device.

摘要： In the disclosed nonreciprocal circuit device, which employs a single-board-type capacitor, the problem of electrode peeling can be avoided. The nonreciprocal circuit device has characteristics such that attenuation is small in the direction of signal transmission and attenuation is large in the reverse direction and has matching capacitors disposed in signal input/output ports. The matching capacitors are formed of single-board-type capacitors including capacitor electrodes formed so as to be opposed each other on both main surfaces of a dielectric substrate with the substrate in between. An outer peripheral edge of a grounding electrode (or another connected electrode), to which a capacitor electrode of the single-board-type capacitor is connected, is positioned inwardly from an outer peripheral edge of the capacitor electrode.

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.

摘要： A nonreciprocal circuit device including a metal case through which a high frequency current is difficult to flow, and a communication apparatus incorporating the nonreciprocal circuit device. The cross section of the metal case has a rectangular-frame shape formed by inwardly bending a substantially rectangular metal plate at four positions at angles of 90 degrees in parallel to the short edges of the metal plate. The top ends of two arms of the metal case are opposed to each other at a specified distance. As a result, the metal case does not form a loop around a permanent magnet and a central electrode assembly.
