    摘要: The invention proposes an H-plane filter with inductive irises which exhibits a quasi-elliptic response while retaining the same compactness as a filter having a Chebyshev response. The invention furthermore makes it possible to use a large number of transmission zeros. For this purpose, there is proposed a waveguide filter comprising at least one cavity delimited by at least two inductive irises. The filter furthermore comprises at least one floating insert 1 placed in one of the inductive irises. The invention is also a process for manufacturing the waveguide filter incorporating at least one insert.

    摘要: The present invention relates to a FINLINE type microwave band-pass filter comprising a waveguide provided with an insulating substrate placed in an E plane of the guide and comprising on at least one of the surfaces, conductive inserts electrically connected to the internal surfaces of the guide which support the substrate and which determine by their dimensions and their positioning on the substrate a Chebyshev type filter response curve. The filter includes at least one cavity in perpendicular short circuit to the substrate, the positioning and the dimensions of the cavity determining a transmission zero on the filter response curve for attenuating the frequencies situated around this zero. Such a filter is used in particular in transmission terminals operating in the Ka band.

    摘要: The invention relates to RF bandpass filters with pseudo-elliptic response. In a filter comprising a dielectric substrate placed in E position in a rectangular waveguide and comprising inserts on one of the surfaces of the substrate are placed conductors linked electrically to the walls of the guide, and on the other surface of the substrate opposite these conducting inserts are placed electrically floating inserts that make it possible to determine zeros in the transmission curve of the filter. This yields a filter exhibiting a response curve of pseudo-elliptic type which improves the rejection of spurious frequencies without increasing the dimensions of the filter.
