The pass band filter has elementary cells (10) with inductive (32) and capacitive (33) sections in a coaxial structure. The capacitive section has a quarter wave resonator (35) in series with the capacitive section providing a high pass filter.

Abstract (fr)

La présente invention concerne un filtre passe-bande. Ce filtre comporte une ou plusieurs cellules élémentaires (10) de type passe-bande placées en série, une cellule élémentaire regroupant un réseau exerçant un filtrage passe-bas composé d'un tronçon inductif (32) et d'un tronçon capacitif (33) en structuré coaxiale et un résonateur quart d'onde (35) en série exerçant un filtrage passe-haut, placé au milieu du tronçon capacitif (33). L'invention s'applique notamment pour des filtres disposés en sortie du tube hyperfréquence dans la chaîne d'émission d'un radar, par exemple à bande étroite. Plus généralement, elle s'applique pour les filtres passe-bande utilisés dans des émetteurs mais aussi dans des récepteurs de systèmes électromagnétiques. <IMAGE>
