Embodiment

[0023] see figure 1 , are all the components of this invention, take the 24JS4750 two-layer ridge waveguide circulator as an example, it is a two-layer ridge waveguide circulator structure, add a layered baffle and matching step structure 5 and ferrite in the main waveguide 3 of the circulator 4. In order to increase the power that the circulator can withstand, there are heat sinks 1 and magnets (2) outside the main waveguide 3 of the circulator, whose functions are to increase the heat dissipation area and form a magnetic circuit respectively. The order of the two-layer circulator structure is as follows: The heat sink 1, the magnetic steel 2, the main waveguide 3, the ferrite 4, the layered separator and the matching step structure 5.

[0024] see figure 2 , is the simulation result of the electrical performance index of the high-power double-layer ridge waveguide circulator. The 24JS4750 standard rectangular double-ridged waveguide has a cutoff frequency of 3.961GHz for ...

Abstract

The invention relates to the technical field of microwave communication, in particular to a high-power multilayer ridge waveguide circulator which comprises cooling fins, magnetic steel, main waveguides, ferrites, layered partition plates and matched step structures, the cooling fins and the magnetic steel are arranged on the outer sides of the main waveguides, and the layered partition plates, the ferrites and the matched step structures are arranged between the adjacent main waveguides. Compared with the prior art, the multi-layer ridge waveguide circulator is formed among the multiple layers of main waveguides through the layered partition plates, the ferrites and the matched step structures, the circulator can bear larger working power, the heat dissipation area is increased and a magnetic circuit is formed through the cooling fins and the magnetic steel, the working efficiency is further improved, the structure is simple, design and assembly are convenient, and the cost is low. And the overall cost is further reduced.

Description

Technical field [0001] The invention relates to the technical field of microwave communication, specifically a high-power multi-layer ridge waveguide circulator. Background technique [0002] A high-power circulator is a device in a microwave radio frequency system that enables one-way transmission of electromagnetic waves. Circulator is generally used between the microwave source and the load to prevent the microwave source from being interfered from the direction of the load, thereby ensuring the stable working condition of the microwave source. In addition, when one port of the three-port circulator is terminated with a matched load, it can be used as an isolator. The isolation is used to shield the equipment on its input side from the conditions on its output side. [0003] Traditional waveguide ferrite circulators usually adopt a bipolar Y-shaped structure. However, the power that these structures can withstand is relatively limited and the structure is complex, which ...
