Abstract

The invention discloses a coupling structure, which comprises a body and a cross coupler, wherein the body has a first face and a second face opposite to the first face, at least a first resonant cavity and a second resonant cavity are dug between the first face and the second face, openings of the first resonant cavity and the second resonant cavity are both located on the first face, the first resonant cavity and the second resonant cavity are separated via a separation wall, the first resonant cavity is internally provided with a first resonator, and the second resonant cavity is internally provided with a second resonator; the cross coupler at least comprises a cross coupling resonant cavity and is arranged on the separation wall, and the cross coupling resonant cavity is internally provided with a third resonator; and signals inside the first resonant cavity and the second resonant cavity are coupled via the cross coupler. According to the above coupling structure, the technical problems that the cross coupling structure in the prior art is complicated in design, and the debugging work in the case of use is tedious can be solved.

Description

technical field [0001] The invention relates to the field of electronic technology, in particular to a coupling structure. Background technique [0002] Due to the rapid development of electronic information, this makes spectrum resources increasingly scarce. As a frequency selection device, the microwave coupling structure is used to separate or recombine different frequencies. In order to make more effective use of limited spectrum resources and improve communication To improve the anti-interference ability of the system, it is necessary to improve the frequency selection ability of the microwave coupling structure. The ideal frequency selection characteristic is: let the required frequency pass completely, let the unwanted frequency completely suppress. In the actual design, only different functions can be used to approximate the ideal situation. Among them, the "generalized Chebyshev function" is a superior function type, which can greatly improve the frequency selectio...
