Abstract
An irreversible circuit module includes a permanent magnet for providing a DC magnetic field for a magnetic member; an assembly having a magnetic member provided with a plurality of conductors being common on one end and serving as input and output terminals for high-frequency signals on the other end; a plurality of load capacitors connected to the conductors, the load capacitors being formed in a laminate having a conductor layer: a first transmission line connected to any of the conductors; and a second transmission line coupled magnetically to the first transmission line. The first transmission line and the second transmission line are included in the laminate. The assembly is received in a hole in the middle of the laminate.
