Embodiment Construction

[0040] The operating power of the conventional non-reciprocal circuit element is, for example, 2.5 W in the forward direction and 0.6 W in the reverse direction, but it is ideal to have an operating power of 5 W in the forward direction. The non-reciprocal circuit element of the present invention can increase its working power without losing its low-loss characteristics in miniaturization, and can obtain a working power of about 5W in the forward direction.

[0041] The irreversible circuit element of the present invention utilizes that when a magnetic body including ferrite and the like is applied with an appropriate DC magnetic field, it acts as an anisotropic medium on a high-frequency electromagnetic field, and makes the high-frequency input to the magnetic body The property of a signal traveling in a direction different from the direction of incidence.

[0042] Embodiments of the present invention will be described below with reference to the drawings.

Abstract

A compact non-reciprocal circuit device capable of handling a high power without impairment of the characteristics. The non-reciprocal circuit device contains a magnetic substrate that exhibits anisotropic behavior by application of a direct-current magnetic field. On the surface of the substrate, strip-lines are disposed at an angle, being insulated with each other. One end of each strip-line is grounded, and the other end of each is connected through a capacitor to a ground. Of the ends connecting the capacitors, one end connects to a termination resistor; the remaining ends connect each to an input terminal and an output terminal. The non-reciprocal circuit device exhibits non-reciprocal characteristics between the input and output terminals. The case of the device contains an insulating thermal conductor that serves as a heat-radiator for the termination resistor and the strip-lines.

Description

technical field [0001] The present invention mainly relates to an irreversible circuit element, in particular to an irreversible circuit element used in a mobile communication device such as a car phone and a mobile phone working in the UHF frequency band and the microwave frequency band, especially a high-power Nonreciprocal circuit components used. Background technique [0002] Due to the small size of the irreversible circuit element, it has been used in mobile communication terminal equipment from a long time ago. [0003] Such as Figure 9 As shown, in a non-reciprocal circuit element, a forward signal input from an input terminal is output to an output terminal through a low-loss path. [0004] On the other hand, if Figure 10 As shown, the signal in the reverse direction input from the output terminal is output to another terminal through a route different from the above-described route, and then absorbed by the terminating resistor connected thereto. Therefore, th...
