Abstract

Filtro passa-banda basato sull'impiego di elementi modulari, di facile costruzione e di basso costo, che realizzano, assiemiati l'uno all'altro in modo opportuno, un numero N di cavità variabile in sede di assiemamento e con suscettanze di accoppiamento regolabili don continuità tra zero e infinito, in modo che la selettività del filtro sia quella desiderata. Esso è essenzialmente costituito (Fig. 4) da cavità risonanti (7) collegate una all'altra da anelli di centraggio (9), da flange (10), tiranti (11) che terminano a vite fissati da bulloni (12), da viti (8). L'invenzione si colloca nel campo tecnico dei componenti passivi a microonde e nel campo applicativo delle telecomunicazioni ad altissime frequenze.Band-pass filter based on the use of modular elements, easy to construct and of low cost, which create, properly assembled to each other, a number N of variable cavities in the assembly and with adjustable coupling susceptions don continuity between zero and infinity, so that the selectivity of the filter is the desired one. It is essentially made up (Fig. 4) of resonant cavities (7) connected to each other by centering rings (9), by flanges (10), tie rods (11) which end with screws fixed by bolts (12), by screws (8). The invention is placed in the technical field of passive microwave components and in the field of telecommunications at very high frequencies.
