PSEUDO-ELLIPTICAL FILTER IN THE MILLIMETER FIELD CARRIED OUT IN WAVEGUIDE TECHNOLOGY

摘要

The invention relates to a pseudo-elliptical filter comprising resonant cavities (30 to 35) positively coupled together (36 to 40), the signal input and output of each cavity (30 to 35) being at 90 deg. one from the other. The filter comprises at least one signal retro-coupling between two of these cavities (30, 33; 32, 35), produced in the form of a waveguide (47; 48). BR/ The invention s applies to pseudo-elliptical filters in the millimeter band.
