Abstract (en)
[origin: WO2007031639A1] The invention concerns a waveguide filter (200<SUP>NP</SUP>) for microwaves, characterized in that it has, at least on part of its length, a cross-section having two mutually non-parallel opposite sides (111, 111'), for example trapezoid. The use of such a shape enables the power threshold for forming self-maintained electron avalanche discharges to substantially increased and satisfactory filtering properties to be obtained. The invention also concerns the use of such a filter in a high-power microwave transmitter operating in X and Ka bands, in particular for space applications.
