Abstract

The invention provides a minitype broadband throttling device used for a transmission shaft in a guided wave system, which comprises an inner wall 1, a casing 2, a base 3 and a medium gasket 4 of the throttling device, wherein the top of the inner wall 1 of the throttling device is connected with the casing 2 of the throttling device, and the casing 2 of the throttling device is connected with the base 3 of the throttling device; the inner wall 1 of the throttling device is positioned by the medium gasket 4; and a transmission shaft 5 is positioned in the center of the throttling device, and the transmission shaft 5 and the throttling device are coaxial. The throttling device has small volume, light weight, easy processing, wide frequency band and little microwave leakage, and is suitablefor an occasion that a mechanical transmission device is introduced into the guided wave system when a microwave system and a mechanical transmission system work synergically.

Description

technical field [0001] The invention relates to the field of microwave transmission, in particular to the field of microwave leak-proof devices, in particular to a small broadband choke device suitable for transmission shafts in waveguide systems. Background technique [0002] The choke device is a device to avoid microwave leakage. At present, choke devices are widely used in the cross-connection of microwave antenna feeder systems, rotary joints in various mechanical scanning radars, non-contact short-circuit pistons, and household microwave ovens. They are key devices in microwave engineering. [0003] The choke structure appeared earlier and has a wide range of applications. Since Ragan proposed the design of coaxial choke rotary crosslink [G.L.Gagan, Microwave Transmission Ciranits, M.I.T.Rad.Lab.Ser., McGraw-Hill Book, Co.Inc., New York, N.Y., vol.9; 1948] Afterwards, many reports on the improved design of the choke structure were produced, and Grantion.J.P made a de...
