Abstract

Selon un mode de réalisation, la présente invention concerne un filtre diélectrique à mode électromagnétique transversal (TEM). Une structure de suppression d'extrémité proche est disposée à l'intérieur du filtre, et la forme, la position et la taille de la structure de suppression d'extrémité proche sont conçues de manière souple pour atteindre le zéro de transmission ou zéro cavité, supprimer un signal de radiofréquence (RF) à une extrémité haute fréquence ou extrémité basse fréquence en dehors d'une bande de transmission de filtre. Ledit filtre présente une bonne performance de suppression en extrémité proche. Un mode de réalisation de la présente invention concerne en outre un module RF et une station de base.
