Embodiment Construction

[0021] Hereinafter, the embodiments of the present invention will be described in detail with reference to the accompanying drawings. The examples cited are only used to explain the present invention and are not used to limit the scope of the present invention.

[0022] A coaxial high-power ferrite circulator includes a body. The side of the body has three ports for installing a waveguide coaxial converter, and the three ports are recessed inward to form three chambers, The three cavities extend and communicate with each other to form a Y-shaped waveguide cavity.

[0023] In one embodiment, the body may be a whole body, and the Y-shaped waveguide cavity is processed inside the body. The center of the Y-shaped waveguide cavity is sequentially provided with a first ferrite 4, a spacer 5 and a second ferrite 6 from top to bottom. The first ferrite 4 and the second ferrite 6 both have Three protrusions respectively directed to the three ports, each of the protrusions is provided with ...

Abstract

The invention relates to a coaxial high power ferrite circulator. The coaxial high power ferrite circulator includes a device body, wherein three ports for mounting waveguide coaxial converters are arranged at the side surface of the device body; the three ports are concaved and extended inward to be mutually communicated to form a Y-shaped waveguide cavity; a first ferrite, a pad and a second ferrite are arranged at the center of the Y-shaped waveguide cavity from top to bottom successively; the first ferrite and the second ferrite are each provided with three lugs respectively pointing to the three ports; each lug is provided with a partition piece; the upper and lower surfaces of the device body are each provided with a groove; and permanent magnets are arranged in the grooves. By means of the Y-shaped waveguide cavity and the waveguide coaxial converters, the bearing power of the coaxial high power ferrite circulator can be improved. By means of the partition pieces, microwave matching between the ferrites and each waveguide coaxial conversion can be obtained while the size of the Y-shaped waveguide cavity can be compressed and the volume of the device body can be reduced. The coaxial high power ferrite circulator removes the center conductor of a traditional coaxial circulator, and can improve the capability, of bearing the microwave power, of the circulator.

Description

Technical field [0001] The invention belongs to the technical field of communication, and relates to a ferrite circulator, in particular to a coaxial high-power ferrite circulator. Background technique [0002] At present, common coaxial ferrite circulators include: cavity, ferrite, gasket, permanent magnet, center conductor and coaxial connector. Because the microwave power is concentrated near the center conductor, the microwave power that the device bears is relatively low. Summary of the invention [0003] The purpose of the present invention is to provide a coaxial high-power ferrite circulator, which solves the problem of low microwave power of current devices. [0004] In order to achieve the above objectives, the technical solutions adopted by the present invention are as follows: [0005] A coaxial high-power ferrite circulator includes a body. The side of the body is provided with three ports for installing a waveguide coaxial converter. The three ports are recessed inward...
