Abstract
Isolators are disposed such that DC magnetic fields of permanent magnets intensity with each other, and thus, the input impedance of non-reciprocal circuitsand(regulating means) is reduced. Accordingly, the impedance conversion ratio between the output impedance of amplifying meansand the input impedance of the regulating meansis reduced to be relatively small. Thus, by simplifying the configuration of matching meansdisposed between the amplifying meansand the regulating means, the insertion loss of the matching meanscan be reduced, thereby enhancing the efficiency of a circuit module. Additionally, it is possible to dispose the non-reciprocal circuitsandclose 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 moduleand accordingly reducing the size of the circuit module
