Abstract
A non-reciprocal circuit device includes a ferrite arranged to receive a direct-current magnetic field from a permanent magnet, a first central electrode and a second central electrode arranged on the ferrite. The non-reciprocal circuit device further includes matching capacitors and a terminating resistor. When high frequency signals flow in a reverse direction, power consumption at the first central electrode is increased by decreasing an equivalent parallel resistance Rp of the first central electrode, in relation to power consumption at the terminating resistor.
