Half-cavity waveguide circulator

Abstract

The invention discloses a waveguide circulator with a half cavity structure, belonging to the technical field of microwave components, comprising an upper cavity, a lower cavity and a connector. The upper cavity and the lower cavity are connected through the connector. The upper cavity is provided with a rotary magnetic substrate and a permanent magnet, and the lower cavity is provided with only apermanent magnet. The half-cavity structure waveguide circulator and the adapter can be used for forming a new waveguide circulator power test system required by a low power source. The problem thatthe waveguide circulator cannot carry out average power test and limit power evaluation due to lack of a power source can be solved by adopting the system for test. At the same time, the popularization of this technology can reduce the demand of power source in power test and limit power evaluation test, reduce the test cost, reduce the damage of power system to test personnel, and increase the protection of power test system itself.

Description

technical field [0001] The invention relates to the technical field of microwave components, in particular to a waveguide circulator with a half-cavity structure. Background technique [0002] With the continuous updating of technology and the continuous increase of product power, the requirements for product power test are also increasing. In order to ensure the reliability of the product, the waveguide circulator needs to be verified by power test during the production process. The continuous increase in power demand has led to the following problems in the power test. [0003] (1) Lack of power source: The application of the waveguide circulator needs to be derated according to the corresponding specifications, usually 75%. Therefore, the corresponding products proposed by the system exceed the power of the system power source by about 33%, so the lack of power source often occurs. If the power test cannot be carried out, the original power source is used for the test, ...

AI Technical Summary

Problems solved by technology

[0003] (1) Lack of power source: The application of the waveguide circulator needs to be derated according to the corresponding specifications, usually 75%. Therefore, the corresponding products proposed by the system exceed the power of the system power source by about 33%, so the lack of power source often occurs. If the power test cannot be carried out, the original power source is used for the test, and the power requirements specified in the test cannot be met.

[0004] (2) High risk and cost of the test: the higher the power, the higher the corresponding heat dissipation requirements, the higher the energy consumption, and the higher the failure rate of test components

The power test needs to simulate the actual use state, and strict assessment, but the total reflection scheme cannot monitor the electric field distribution inside the circulator in real time, and the electric field distribution inside the product may be very different from the actual use state
