Abstract
The present invention relates to a micro-subminiature microwave gyromagnetic circulator comprising a housing and a first ceramic ring ferrite, a central conductor, a second ceramic ring ferrite and a medium ferrule mounted inside the housing; the medium ferrule comprises a pin, and a foot of the central conductor is provided with a through-hole matching the pin; the pin comprises an extension and a fixed portion which are connected, wherein the diameter of the extension is smaller than the diameter of the fixed portion, the pins and the feet are welded at the through-holes via solder paste, and a tin-containing tank is provided at the connection between the extension and the fixed portion. The microwave gyromagnetic circulator can be micro-subminiature without decreasing bandwidth. The structure stability and conduction stability of the microwave gyromagnetic circulator are improved by welding the central conductor to the pin and providing a tin-containing tank on pin.
