The invention relates to a coaxial and high-power ferrite switch. The coaxial and high-power ferrite switch comprises a device, wherein three ports are arranged in a side surface of the device and areused for installing waveguide coaxial converters, the three ports are inwards sunken and extend to communicate with one another so as to form a Y-shaped waveguide cavity, a first gasket, a ferrite and a second gasket are sequentially arranged in the center of the Y-shaped waveguide cavity from top to bottom, the ferrite is provided with three protruding parts respectively facing the three ports,each protruding part is provided with an isolation sheet, a groove is formed in an upper surface of the device and is used for installing a driving circuit, a plurality of threading holes are formed in the ferrite, and an excitation coil sequentially penetrates through each threading hole, penetrates out of a side wall of the Y-shaped waveguide cavity and is connected with the driving circuit. Byemploying the Y-shaped waveguide cavity and the waveguide coaxial converters, the bearing power of the coaxial switch is improved; by employing the isolation sheets, microwave matching between the ferrite and each waveguide coaxial converter is obtained; and by the coaxial and high-power ferrite switch, a central conductor of a traditional coaxial switch is removed, and the capability of bearing microwave power of the device is improved.
Description
technical field [0001] The invention belongs to the technical field of communication, and relates to a ferrite switch, in particular to a coaxial high-power ferrite switch. Background technique [0002] The common coaxial ferrite switch includes a cavity, a ferrite, a central conductor, a coaxial connector, an excitation coil and a driving circuit. Since the microwave power is concentrated near the center conductor, the microwave power that the device bears is relatively low. Contents of the invention [0003] The purpose of the present invention is to provide a coaxial high-power ferrite switch to solve the problem of low microwave power of the current device. [0004] In order to achieve the above object, the technical scheme that the present invention takes is as follows: [0005] A coaxial high-power ferrite switch, comprising a body, the side of the body has three ports for installing waveguide coaxial converters, the three ports are recessed inward and extend to co...
