Abstract
Official abstract text for this publication.
Isolators are disposed such that DC magnetic fields of permanent magnets intensity with each other, and thus, the input impedance of non-reciprocal circuits 3 a and 3 b (regulating means 3 ) is reduced. Accordingly, the impedance conversion ratio between the output impedance of amplifying means 2 and the input impedance of the regulating means 3 is reduced to be relatively small. Thus, by simplifying the configuration of matching means 4 disposed between the amplifying means 2 and the regulating means 3 , the insertion loss of the matching means 4 can be reduced, thereby enhancing the efficiency of a circuit module 1 . Additionally, it is possible to dispose the non-reciprocal circuits 3 a and 3 b close to each other so that the DC magnetic fields of the permanent magnets can intensity with each other, thereby increasing the design flexibility of the circuit module 1 and accordingly reducing the size of the circuit module 1.
First claim
Opening claim text (preview).
The invention claimed is: 1. A circuit module comprising: amplifying means for amplifying a plurality of types of signals; regulating means for restricting a passing direction of each of the plurality of types of signals amplified by the amplifying means to one direction, wherein the regulating means includes a plurality of non-reciprocal circuits individually disposed for the plurality of types of signals; and matching means for matching an output impedance of the amplifying…
