Problems solved by technology

[0011] a) Reducing the micro-discharge threshold through structural design, this method requires a sufficiently large physical size, but because the spaceborne equipment is limited by the rocket load capacity, there are usually requirements for miniaturization and light weight, so the cost of this method high cost;
[0012] b) The micro-etching process and photolithography process require professional process equipment and process parameters, which requires a large investment, and some structures are not suitable for use;

Abstract

The invention discloses a high-power circulator for L-waveband micro-discharge suppression of a satellite, belonging to the technical field of microwave components and parts. The high-power circulatorcomprises a circulator main body and a connector connected with two ends of the connector main body, wherein the connector main body mainly comprises an upper cavity and a lower cavity which are mutually connected, an upper medium and a lower medium are respectively arranged in the upper cavity body and the lower cavity body, the inside of the connector is formed by the surrounding of the inner sides of the upper medium and the lower medium, substrates are arranged on the inner sides of the upper medium and the lower medium, and central conductors are arranged on the substrates; and a connector inner conductor and a connector medium are arranged in the connector, the central conductor is connected with the connector inner conductor, and the connector medium extends into the circulator andis staggered with the upper medium and the lower medium. According to the high-power circulator, the micro-discharge can be effectively suppressed, the structure and boundary dimension of a product are not limited, the high equipment input is not required, the process is simple, and the high-power circulator is suitable for popularization.

Description

technical field [0001] The invention relates to the technical field of microwave components, in particular to a high-power circulator for L-band micro-discharge suppression satellites. 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 cause the entire satellite to fail, which is extremely harmful. This kind of discharge phenomenon is called micro-discharge. In order to ensure the normal operation of spaceborne equipment within the lifetime, effective measures must be taken to suppress the generation of micro-discharge. [0003] The microdischarge phe...
