Research on Multipactor of Microwave High Power Modules

Based on production mechanism of multipactor effect,multipactor-proofing design of satellite-borne microwave high power modules is introduced.Many measures are taken to improve multipactor threshold of microwave active circuits.The validity of multipactor-proofing design is proved by vacuum multipactor experiment finally.Based on it test data of microwave high power modules are offered.The module is applied in integrated solid-state transmitters on satellite-borne radar.Its output peak power is greater than 500W and it has good environmental adaptability in vacuum.
