The embodiment of the invention discloses a corrugated waveguide filter. The corrugated waveguide filter comprises a rectangular waveguide, and two groups of corrugated waveguide structures which are positioned on the outer side surfaces of two opposite side walls of the rectangular waveguide. Each corrugated waveguide structure comprises a middle partition plate extending in the axial direction of the rectangular waveguide, a first partition plate and a second partition plate, wherein the first partition plate and the second partition plate extend from the middle partition plate to the two sides of the middle partition plate. The first partition plate and the second partition plate are symmetrically arranged relative to the middle partition plate; in the extension direction of the rectangular waveguide, the corrugated waveguide structures comprise the plurality of first partition plates arranged at intervals and the plurality of second partition plates arranged at intervals; a first corrugated waveguide inner cavity is formed between every two adjacent first partition plates, and a second corrugated waveguide inner cavity is formed between every two adjacent second partition plates; and the first corrugated waveguide inner cavity and the second corrugated waveguide inner cavity penetrate through the side wall of the rectangular waveguide and are communicated with the inner cavity of the rectangular waveguide. The filter still works stably and normally when the peak power is more than 30kW, and the peak power capacity is improved by more than 6 times.
Description
technical field [0001] The invention relates to the technical field of microwave components. More specifically, it relates to a corrugated waveguide filter. Background technique [0002] In microwave systems such as mixers and frequency multipliers, in addition to obtaining the main signal of the required operating frequency, several interference signals of higher harmonic frequencies are also excited. For example, at frequency f 0 After the excitation signal of / 2 passes through the frequency multiplier, the working frequency is obtained as f 0 main signal, but also produces harmonics at 3f 0 / 2, 4f 0 / 2 interference signal, where the harmonic frequency is 4f 0 The interference signal amplitude of / 2 is small, and the impact on the system is negligible, while the harmonic frequency is 3f 0 The interference signal of / 2 has a large amplitude, which will have an adverse effect on the use of the system. In order to ensure the normal and stable operation of the system, i...
