Novel high power water load

Abstract

The invention relates to a novel high power water load. The novel high power water load comprises a waveguide radiation horn mouth, a base, a spiral water chamber, a terminal short circuit block, and a protection housing disposed on the outer side of the spiral water chamber. Spiral type flowing water used as a microwave absorber is disposed in the spiral water chamber. The front end of the spiral water chamber is in the shape of a cone, and the rear end of the spiral water chamber is in the shape of a cylinder. One end of the waveguide radiation horn mouth is fixedly connected with an output radiation waveguide, and the other end of the waveguide radiation horn mouth is connected with the base. The other end of the base is connected with the rear end of the spiral water chamber and the bottom part of the protection housing, and the side of the base connected with the spiral water chamber is provided with a groove embedded in the rear end bottom part of the spiral water chamber. The side of the rear end of the spiral water chamber connected with the base is a water inlet, and the side of the front end of the spiral water chamber is a water outlet. The front end of the terminal short circuit block is in the shape of a cone, and is embedded in the front end of the spiral water chamber, and the rear end of the terminal short circuit block is connected with the top part of the protection housing. The water load is capable of satisfying use requirements of a high power millimeter wave electric vacuum device, and at the same time, the broadband low reflection of the water load is realized.

Description

technical field [0001] The invention belongs to the technical field of high-power microwaves and millimeter waves, and specifically relates to a novel broadband high-average-power-capacity water load applied in high-power millimeter-wave systems. Background technique [0002] In recent years, with the development of high-power millimeter-wave technology, high-power, broadband millimeter-wave electro-vacuum devices have played an important role in military and scientific fields such as high-resolution millimeter-wave imaging, millimeter-wave countermeasures, and radar transmitter systems. In order to ensure the working performance of high-power millimeter-wave devices, it is necessary to test the output power of the processed and assembled finished products. However, the average output power of the high-power millimeter-wave device test system can reach tens of kilowatts or even hundreds of kilowatts. Therefore, in order to avoid electromagnetic environmental pollution and h...

AI Technical Summary

Problems solved by technology

However, due to the large volume of the water chamber, the water flow velocity near the inner wall of the water chamber is relatively slow, resulting in a small load power capacity of the improved radiant water

The maximum average power capacity of the improved radiant water load structure is 5kW, which cannot meet the high-power requirements of tens of kilowatts for high-power millimeter-wave electric vacuum devices
