Abstract

Sistema di coppie di filtri passa banda per reti di combinazione di segnali a radio-frequenza (microonde) in particolare per reti di combinazione di segnali provenienti da N trasmettitori (TXi) che, ciascuno tramite un suo filtro (Fi), è accoppiato ad una linea comune (L') diretta ad un'antenna, ogni filtro della coppia essendo a cavità risonante formata da più pareti poligonali, contenente almeno un risonatore dielettrico e comportante connettori di entrata ed uscita come pure un organo di accoppiamento elettro-magnetico, caratterizzato dal fatto che ogni coppia è formata da due cavità aperte su un lato, e disposte da una parte e dall'altra di una piastra centrale comprendente un nucleo e due facce maggioritarie esterne, ogni faccia formando la parete aperta della cavità, ed il detto nucleo ospitando al suo interno i mezzi dì regolazione dell'organo di accoppiamento elettro-magnetico. (FIG. 6).System of pairs of band-pass filters for combination networks of radio-frequency (microwave) signals, in particular for combination networks of signals from N transmitters (TXi) which, each through its own filter (Fi), is coupled to a common line (L ') directed to an antenna, each pair filter being a resonant cavity formed by several polygonal walls, containing at least one dielectric resonator and comprising input and output connectors as well as an electro-magnetic coupling member, characterized by the fact that each pair is formed by two cavities open on one side, and arranged on one side and the other of a central plate comprising a core and two external majority faces, each face forming the open wall of the cavity, and the said core housing inside the means for adjusting the electro-magnetic coupling member. (FIG. 6).
