Nonreciprocal circuit device and telecommunications apparatus including the same

摘要

A nonreciprocal circuit device includes a box-like yoke consisting of upper and lower yokes. The yoke accommodates a magnetic assembly consisting of a magnetic body and first to third line conductors, chip capacitors connected to ends of the line conductors, and a magnet. The first and second line conductors are input and output terminals, and an end of the third line conductor is connected to a terminating chip resistor. The chip resistor is longitudinally disposed such that its long sides are substantially perpendicular to a line between ends of the input and output terminals. The end of the third line conductor is connected to a terminal electrode on the hot side of the terminating chip resistor. A terminal electrode on the earth side of the terminating chip resistor is directly connected to the lower yoke, and a notch is formed in the lower yoke under the hot side terminal electrode.
