Embodiment Construction

[0028] The present invention will be further described below in conjunction with accompanying drawing.

[0029] A design method for suppressing micro-discharge of a space-borne high-power microwave ferrite circulator comprises the following steps: (A) coating an insulating layer inside the circulator; (B) vacuumizing the circulator. As a further improvement of the present invention: the circulator is a microwave ferrite circulator with a stripline / coaxial structure, and the use state of the circulator is a spaceborne high power condition.

[0030] As a further improvement of the present invention: in the step (A), silicon rubber is coated between the strip wire and the cavity wall inside the circulator, the surface of the strip wire and the surface of the gyromagnetic substrate.

[0031] In the step (B), put the circulator into the vacuum tank, and then evacuate it for 10-30 minutes. The time can be adjusted according to the actual situation, for example, the time is between 1...

Abstract

The invention relates to the field of circulators, and particularly discloses a design method for restraining micro discharging of a satellite-borne high-power microwave ferrite circulator. The method comprises the following steps: filling silicone rubber in the internal gap of the circulator; discharging the gas in the silicone rubber under vacuum (the vacuum degree is less than or equal to 5Pa); and finally carrying out assembling and cavity closing at normal temperature according to a universal process requirement. The method provided by the invention has the beneficial effects of being convenient to operate and low in cost, and being capable of effectively restraining the micro discharging phenomenon of the microwave ferrite circulator under thermal vacuum after a certain power.

Description

technical field [0001] The invention relates to the field of circulators, in particular to a design method for suppressing microdischarge of a space-borne high-power microwave ferrite circulator. Background technique [0002] With the rapid development of satellite technology, the requirements for miniaturization, light weight and high power of satellite-borne microwave equipment are getting higher and higher. When the satellite works in a vacuum environment, the microwave circuit is prone to appear different from the ground with the increase of power. The discharge phenomenon under normal pressure will seriously affect the signal transmission of the satellite and even lead to the failure of the entire satellite, which is extremely harmful. This discharge phenomenon is called micro-discharge. In order to ensure the normal operation of the satellite-borne equipment within the service life, effective measures must be taken Suppresses the generation of micro discharges. [000...
