Satellite-borne compact coaxial T switch assembly

Abstract

The invention relates to a satellite-borne compact coaxial T switch assembly. Thesatellite-borne compact coaxial T switch assembly is used in a satellite effective load switch network, can be independently used as a component to back up a key single machine according to user requirements to improve the reliability of a whole satellite, and can also be combined with other switch assemblies to form a more complex switch network to realize a more complex connection state. The size and the weight of the assembly can be effectively reduced by adopting a common bottom plate structural form, six switch shells are mounted on the same bottom plate, and various switch remote control and telemetering instruction terminals are connected to a low-frequency connector through leads, so that remote control and telemetering acquisition can be conveniently carried out on the switch; and the low-frequency connector further integrates switch control and telemetering signals. The structure of the switch assembly can be extended into five-in-one, four-in-one, three-in-one, two-in-one assemblies and other forms, the size and weight of the switch assembly can be effectively reduced, the function of the switch is not affected, and the integration of the product is improved to a great extent.

Description

technical field [0001] The invention relates to a space-borne compact coaxial T switch assembly, which belongs to the technical field of microwave passive products. Background technique [0002] The coaxial T-shaped microwave switch has the characteristics of multiple working states, and is one of the key components of the satellite payload. Its main function is to switch the radio frequency channel, and perform ring backup of a fixed number of hardware through the switch to achieve more connections. state, when part of the hardware fails, the backup hardware in the system can replace the faulty hardware by switching the working state of the microwave switch to improve the reliability of the whole star. The three working states of the coaxial T-type microwave switch are as follows: figure 1 shown. [0003] As communication and navigation satellites have increased their payload channel capacity requirements year by year in recent years, there are more and more requirements ...

AI Technical Summary

Problems solved by technology

For current high-throughput, multi-channel communication satellites, the three working states of a single coaxial T-shaped microwave switch in the actual transponder subsystem cannot meet the needs of multi-channel ring backup

The integration of multiple coaxial T-shaped microwave switches does not meet the requirements of miniaturization and light weight on the star
