ABSTRACT:
A two-port non-reciprocal circuit device has one end of a first central electrode electrically connected to an input port and the other end thereof electrically connected to an output port. One end of a second central electrode is electrically connected to the output port and the other end thereof is electrically connected to a ground port. A resonant capacitor and a terminating resistor are electrically connected in parallel between the input port and the output port. A resonant capacitor is electrically connected between the output port and the ground port. Matching capacitors for impedance matching are electrically connected between the input port and an input terminal and between the output port and an output terminal, respectively. A coupling capacitor element is electrically connected between the input terminal and the output terminal.
