Problems solved by technology

The existing waveguide switch guide path is a uniform waveguide path, so the design of multiple paths will increase the volume of the rotor, thereby increasing the overall volume of the switch, which does not meet the requirements of lightweight aerospace products
In addition, the increase in the number of channels will lead to increased signal interference and degraded performance

example

[0039] Example: Taking the BJ320 type waveguide switch as an example, the depth of the axial choke groove 10 is selected as 2.2mm and the width is 0.6mm. The circumferential choke groove 11 has a depth of 2.2mm and a width of 0.6mm. The polarization choke groove 12 has a depth of 1mm and a width of 0.4mm. It can meet the requirements of isolation greater than 70dB and voltage standing wave ratio less than 1.03.

[0040] The invention has simple structure, small size, light weight, and good microwave transmission performance. It has been successfully applied to many in-orbit satellite models such as XX navigation satellite project, and realized mass production. It has significant military, economic and social benefits, and has broad application prospects. .

Abstract

A miniature multi-channel waveguide switch comprises an electromagnetic system and a guide system, wherein a guide rotor in the guide system adopts a mode of combining uniform bent waveguide paths and a non-uniform straight waveguide path, so that the path width is reduced, the switch sizeis greatly reduced, and the purpose of the miniature switch is achieved. Further, a non-uniform straight waveguide structure adopts a gradually-changing compensation method, the parameter deterioration brought by discontinuity is reduced, compensation is achieved by optimizing an axial choke groove, a circumferential choke groove and a polarization choke groove, and the stability of microwave performance is ensured.

Description

technical field [0001] The invention relates to a waveguide switch, in particular to a miniaturized multi-channel waveguide switch. Background technique [0002] As a mechatronic component, the waveguide switch is mainly used for the selection of the microwave signal transmission path, the on-off of the waveguide transmission energy or the switching between channels. It is widely used as a backup switch for high-power output radar and communication transmitters. At the same time, it is also widely used in microwave launch equipment and microwave measurement and control projects of satellite communication systems. It is often used to realize the 1:1 backup of core microwave equipment or the switching between the antenna and the unloading channel on the microwave power signal. It is one of the key components of the satellite signal transmission system. With the continuous improvement of the frequency of communication and control signals of various weapons and equipment, the f...
