Abstract
A non-reciprocal circuit element capable of improving an isolation characteristic without increasing an insertion loss includes a permanent magnet, a ferrite arranged to receive a direct-current magnetic field from the permanent magnet, and first and second center electrodes disposed on the ferrite. One end of the first center electrode is connected to an input port, whereas the other end is connected to an output port. One end of the second center electrode is connected to the output port, whereas the other end is connected to a ground port. A matching capacitor and a resistor are connected between the input port and the output port. An inductor and a capacitor constituting an LC resonant circuit are connected in series with the resistor.
