Nonreciprocal circuit device and communication apparatus incorporating same

Abstract

A nonreciprocal circuit device having good characteristics capable of maintaining constantly stable and reliable connections even when a high temperature is applied, and a communication apparatus incorporating the nonreciprocal circuit device. The nonreciprocal circuit device can be made compact at a low cost and can obtain a large attenuation at a predetermined frequency band. In the nonreciprocal circuit device, an upper yoke is connected to a lower yoke, a bottom grounded part of a magnetic assembly is connected to the lower yoke. In addition, ports P1 and P2 of first and second central conductors, the hot-side electrodes of first and second capacitors, and input/output terminals are connected each other, and the port P3 of a third central electrode, the hot-side electrode of a third capacitor, and the hot-side electrode of a terminating resistor R are connected to each other. Furthermore, the cold-side electrodes of the first to third capacitors, the cold-side electrode of the terminating resistor R, and a ground terminal are connected to each other. A conductive adhesive is applied for these connections.
