Nonreciprocal circuit device and communication apparatus

Abstract

The present invention provides a nonreciprocal circuit device which allows the relationship between the input and the output to be reversed using the identical terminal layout on a mounting substrate, only by preparing for a single type of nonreciprocal circuit device, and also provides a communication apparatus using this nonreciprocal circuit device. In this reciprocal circuit device, a plurality of centeral conductors are disposed on a ferrite on which DC magnetic field is to be applied, in a state of intersecting one another, matching capacitors are each connected between the ports of the centeral conductors and grounds, and a terminating resistor is connected between a predetermined port and a ground. In a resin case 7, input/output terminals which are conductively connected to the respective ports are disposed at substantially rotation-symmetrical positions with respect to the center of the bottom surface of the resin case.
