Abstract: In a non-reciprocal circuit device, a first center conductor, a second center conductor, and a third center conductor are disposed on a ferrite, to which a direct current magnetic field is applied by a permanent magnet, so as to be insulated from one another and so as to intersect with one another. One end of the first center conductor defines a first port, one end of the second center conductor defines a second port, and one end of the third center conductor defines a third port. The first port is connected to a first terminal, the second port is connected to a second terminal, and the third port is connected to a third terminal. The other ends of the respective center conductors are connected to one another, which is connected to a ground. Capacitance elements are connected in parallel to the respective center conductors.

Abstract: In a non-reciprocal circuit element, first to third center conductors intersect one another in an insulated state around a microwave magnetic body, and first ends of the first to third center conductors define first to third ports. A first capacitance element is connected to the first center conductor in parallel and a second capacitance element is connected to the second center conductor in parallel, and the other ends of the first to third center conductors are connected to one another and are grounded via a first inductance element and a third capacitance element that are connected in series. A second inductance element is connected to one end of the center conductor in parallel, and the other end of the second inductance element is grounded. A fourth capacitance element is connected to a connection point between the one end of the center conductor and the second inductance element, and the other end of the fourth capacitance element is connected to a third terminal.
