Title (EN) ACOUSTIC FILTER DEVICE
(FR) DISPOSITIF DE FILTRE ACOUSTIQUE
Abstract:
(EN) An acoustic filter device comprises a filter chip with filter elements that are arranged in a series signal line as well as in parallel branches connected to a ground termination each. A carrier substrate for the filter chip comprises grounding vias for connecting the ground terminations to an external ground. At least one primary grounding inductor is coupled between one of the ground terminations and the external ground and additional tunable elements are coupled between a ground termination and the external ground.
(FR) Dispositif de filtre acoustique comprenant une puce de filtre avec des éléments de filtre qui sont agencés dans une ligne de signal en série ainsi que dans des branches parallèles reliées à une terminaison de masse chacune. Un substrat de support pour la puce de filtre comprend des trous d'interconnexion de mise à la masse pour connecter les terminaisons de masse à une masse externe. Au moins une bobine d'induction de mise à la terre primaire est couplée entre l'une des terminaisons de masse et la masse externe et des éléments réglables supplémentaires sont couplés entre une terminaison de masse et la masse externe.
