Abstract: front page image
(EN)Disclosed is a duplexer for which filter loss is reduced. The duplexer is provided with at least two filters (F1 and F2) having different passbands, connected to a common terminal; wherein at least one of the filters (F1 and F2) includes a plurality of series resonators (S1 to Sn) connected in series to a line that connects the input terminal and output terminal of the filter, and parallel resonators (P1 to Pm) connected in parallel to the line; wherein an inductance (L1) is connected in parallel to at least one of the series resonators, and the series resonator (S1) connected in parallel to the inductance (L1) is divided under a plurality of resonators (S11 to S13) connected in series.
(FR)L'invention concerne un duplexeur au moyen duquel on réduit la perte de filtrage. Le duplexeur est doté d'au moins deux filtres (F1 et F2) ayant des bandes passantes différentes, connectés à une borne commune. Au moins l'un des filtres (F1 et F2) comprend une pluralité de résonateurs série (S1 à Sn) connectés en série à une liaison reliant la borne d'entrée et la borne de sortie du filtre, et des résonateurs en parallèle (P1 à Pm) montés en parallèle sur la liaison. Une inductance (L1) est connectée en parallèle d'au moins l'un des résonateurs série et le résonateur série (S1) connecté en parallèle à l'inductance (L1) est divisé en une pluralité de résonateurs (S11 à S13) connectés en série.
