摘要:
A nonreciprocal circuit device that avoids the problems of increased loss and narrowed frequency bandwidth when used with a low power supply voltage. An isolator (nonreciprocal circuit device) has a plurality of center electrodes (2 through 4) disposed so as to intersect and having a ferrite (5) disposed in alignment with the point of intersection, to which a DC magnetic field HDC is applied. An impedance conversion circuit (6) is added to the port of any one of center electrodes (2 through 4), setting the input impedance Zi to 2
