    摘要: A printed wiring board having at least one connector includes a dielectric substrate that has, on a first face, a first ground plane, and on a second face, at least two transmission lines between which the connector and a footprint are mounted. The footprint includes a first element positioned between the two transmission lines under the connector. The first element forming with the first ground plane, a capacitive element and, at each extremity of the first element, second elements forming with the first element, a self-inductive and capacitive element. The second elements each extending by a second ground plane, the second ground planes which are connected to the first ground plane.

    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 4-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 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.
