Abstract

L'invention concerne un filtre accordable commandé en tension comportant au moins un résonateur en peigne coaxial qui comprend au moins un trou traversant métallisé, une couche de métallisation de couplage entrée/sortie qui est appliquée sur au moins une surface du/des résonateur(s), au moins un varactor accordable qui est associé au(x)dit(s) résonateur(s), et un composant d'interconnexion pôle-entrée/sortie servant à interconnecter un pôle de filtre du/des résonateur(s) et la couche de métallisation de couplage entrée/sortie. Au moins un point de polarisation DC peut être ménagé pour fournir une tension au(x) varactor(s) accordable(s). Dans un mode de réalisation préféré, le filtre selon l'invention comporte quatre varactors accordables et deux couches de métallisation de couplage entrée/sortie. Ledit filtre accordable commandé en tension peut être monobloc ou se présenter sous la forme de blocs coaxiaux. En outre, dans un mode de réalisation préféré de cette invention, le composant d'interconnexion pôle-entrée/sortie peut assurer un couplage capacitif variable, un couplage inductif variable ou un couplage capacitif et inductif variable.
