ABSTRACT:
An irreversible circuit element is configured by including a magnetic substance, a plurality of central conductors L1to L3, one ends of which are connected to different input/output ports, arranged on the magnetic substance so as to intersect each other while being insulated from each other, a first conductor P1connected to the other ends of all the central conductors L1to L3, a second conductor, a plurality of matching capacitors (each configured by C1to C3) connecting the one end of the central conductors L1to L3and the second conductor and a variable matching mechanism V1, one end of which is connected or integrated with the second conductor, capable of changing reactance between the one end and the other end thereof.
