Abstract: Disclosed is a quasi-circulator using an asymmetric directional coupler. The quasi-circulator using the asymmetric directional coupler according to an embodiment of the present invention may enhance a characteristic of isolating a transmitting signal from a receiving signal with the same characteristic as transmitting signal loss of a symmetric directional coupler in the related art by arranging impedance of each line of a directional coupler asymmetrically.
