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

Embodiment

[0047] Such as Figure 2 to Figure 5 As shown, the present invention is described with a coaxial T switch six-in-one assembly. The original single coaxial T switch weighs 75g, combined into a six-in-one component plus the bottom plate and bracket, the total weight is about 620g, volume: the present invention integrates the base of a single switch, and the driving part and radio frequency part of the coaxial T switch are directly installed on the The 6-in-1 base plate can effectively reduce the volume and weight of the switch. The weight of the 6-in-1 switch after integration is about 450g, and the volume: 133.5×79×63. It can be seen that the volume and weight of the switch are greatly reduced after adopting the form of six-in-one components.

[0048] Due to the structural form of the integrated design of the bottom plate, for a single switch, its control circuit, drive part, radio frequency part, etc. remain unchanged. This method does not affect the design of other modules i...

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 ...
