Embodiment Construction

[0044] The embodiments of the present application provide a high-power circulator to solve the technical problem in the prior art that the performance of the circulator tends to deteriorate or fail when the temperature rises.

[0045] The technical solution in the embodiment of the present application is to solve the above-mentioned technical problems, and the general idea is as follows:

[0046] The temperature of the gyromagnet is detected by setting the temperature detection device, and the current size of the electromagnet is controlled by setting the electromagnetic control device based on the temperature, so as to control the magnetic size of the electromagnet, so as to change the applied bias field The magnetic size is used to compensate the change of the saturation magnetization of the gyromagnet, reduce the influence of temperature rise on the circulator, ensure the normal operation of the circulator, and effectively solve the problem of the circulator in the prior art...

Abstract

The invention discloses a high-power circulator. The circulator comprises: a housing which is provided with an inner cavity, and is provided with a plurality of ports communicated with the inner cavity at intervals; electromagnetic limiting equipment comprising a conductor, a gyromagnet and an electromagnet, wherein the electromagnet is used for forming gyromagnetic characteristics of the gyromagnet by forming an external bias field so as to limit one-way circulating propagation of signals between the ports; temperature detection equipment connected with the electromagnetic limiting equipment so as to detect the temperature of the gyromagnet; and electromagnetic control equipment respectively connected with the electromagnetic limiting equipment and the temperature detection equipment and used for controlling the current of the electromagnet based on the temperature of the gyromagnet, so as to compensate the change of the saturation magnetization intensity of the gyromagnet by changing the magnetism of an external bias field. According to the invention, the technical problem that the performance of the circulator is easy to deteriorate or lose efficacy when the temperature rises in the prior art is effectively solved, and the beneficial effects of stable working condition and long service life of the circulator are realized.

Description

technical field [0001] The invention relates to the field of radio frequency wireless communication, in particular to a high-power circulator. Background technique [0002] A circulator is a multi-port device that transmits incident waves entering any port to the next port sequentially in a direction determined by an applied bias field. Under the action of an external bias field, the gyromagnetic material has magnetic anisotropy (tensor magnetic permeability), and the propagation characteristics of microwave signals passing through a gyromagnet are different in different directions, so that the electromagnetic waves propagating in the gyromagnet are generated. The rotation of the polarization uses this rotation phenomenon to make a circulator. [0003] With the development of the new generation of 5G communication technology, the average power requirement of the circulator is increasing, and it is developing in the direction of miniaturization and low cost. However, the hi...
