Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0026] Such as figure 1 An 18G broadband waveguide circulator, including a waveguide cavity 1, and a cover plate 2 is installed on the waveguide cavity 1. It is different in that: in order to increase the bandwidth, the waveguide cavity 1 is distributed with three waveguides Channel 3, three waveguide channels 3 are distributed in Y shape, forming a Y shape waveguide structure. Moreover, the edge of the middle converging point of the Y-shaped waveguide structure is a circular cavity structure. Specifically, the central converging point of the Y-shaped waveguide structure is provided with a boss structure, and a ferrite 4 is installed on the boss structure. At the same t...

Abstract

The invention relates to an 18G broadband waveguide circulator which comprises a waveguide cavity, wherein a cover plate is arranged on the waveguide cavity; three waveguide channels are distributed on the waveguide cavity; the three waveguide channels are distributed in a Y shape so as to form a Y-shaped waveguide structure; a boss structure is formed in a middle convergence point of the Y-shapedwaveguide structure; ferrite is mounted on the boss structure; the edge of the middle convergence point of the Y-shaped waveguide structure is of a round cavity structure; a plurality of mounting threaded holes are distributed in the waveguide cavity; and magnetic steel assemblies are connected onto the mounting threaded holes. Therefore, the distance from the magnetic steel units to the ferritecan be effectively adjusted, saturation magnetization is accurately adjusted, and the isolation performance is improved. According to the round cavity structure in the Y-shaped waveguide structure andthe dual-circular truncated cone structure, 30% of bandwidth can be obtained, the ferrite-bearing dielectric constant fluctuates in a range from 13 to 14.5, indicators are qualified, and convenienceis brought to batch production. The round cavity structure in the Y-shaped waveguide structure and the dual-circular truncated cone structure can be adjusted according to actual needs, and the waveguide circulator can be popularized to other frequency band ranges.

Description

technical field [0001] The invention relates to a circulator, in particular to an 18G broadband waveguide circulator. Background technique [0002] With the development of communication system technology, wider frequency band and higher performance circulators are integrated into waveguide duplexers. In the prior art, people commonly use Y-shaped junction triangular steps, and Y-shaped junction-outside double-matching step structural designs. If it is magnetized on one side, there is a problem of narrow bandwidth and difficult improvement of isolation. If it is double-sided magnetization, the bandwidth expansion is also limited, and the high assembly cost is not conducive to cost reduction. [0003] For example, the design bandwidth of 18G single-sided magnetic waveguide circulators common in the industry generally ranges from 17.7 to 20G, and the theoretical design value of isolation is -28dB. According to the actual ferrite material parameters, the tolerance analysis wi...
