Abstract

The invention provides a coaxial waveguide switch which comprises a waveguide, a coaxial connector and an impedance conversion block. One end of the waveguide is opened, and the other end of the waveguide is closed. The waveguide is provided with a plurality of stages of step-like pits facing the interior of the waveguide. The heights of the step-like pits are sequentially decreased from the closed end to the other end of the waveguide. The impedance conversion block is located in the waveguide and connected to the step-like pit of the topmost layer. The coaxial connector is connected to the closed end of the waveguide, the axial direction of the coaxial connector is identical with the electromagnetic wave transmission direction of the waveguide, and the coaxial connector extends into the waveguide and is inserted into the impedance conversion block. By means of the mode, impedance matching can be achieved by utilizing the structure of the waveguide.

Description

technical field [0001] The invention relates to the technical field of waveguide conversion, in particular to a coaxial waveguide converter. Background technique [0002] In order to reduce the insertion loss during the conversion process between the waveguide and the coaxial line, the method adopted in the prior art is to set a stepped impedance transformation block in the waveguide, and directly insert the coaxial connector into the impedance transformation block in the waveguide. Therefore, an impedance transformation block must be set in the waveguide, and the position of the impedance transformation block cannot be changed once determined. However, in actual processing, the connection between the impedance transformation block and the waveguide is not firm, and often moves during handling or installation. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a coaxial waveguide converter, which can realize imped...
