technical field [0001] The invention relates to a drive device for a satellite-borne microwave switch, which belongs to the field of mechanical design. Background technique [0002] The main function of the satellite-borne microwave switch is to realize the transmission and switching of the microwave signal path of the satellite system. It is a device that uses vacuum isolation and switches microwave signals through mechanical actions. The radio frequency structure of the electromechanical microwave switch for aerospace uses the electrical contact structure of the reed contact, and the on-off switching control of the microwave signal is realized through the on-off of the reed and the conductor contact.

If it is less than the limit value, it will cause potential electrical contact failure,...

AI Technical Summary

Problems solved by technology

[0003] Since the product is used in the aerospace environment, it must meet strict mechanical performance indicators, which involves the reed retention force when the switch is turned on. If it is less than the limit value, it will cause potential electrical contact failure, resulting in total reflection of the microwave signal. The entire chain road failure

The existing microwave switch only relies on the magnetic steel on the reed to provide the driving force because the contact is connected. Due to the limitation of electromagnetic performance and structure, the driving force is low, resulting in a low contact force, which is smaller than that of conventional relays, resulting in a decrease in contact resistance. unstable
