Abstract:
(EN) A multiplexer (1) includes a plurality of elastic wave filters connected to a common connection terminal. In a transmission side filter (13) among the plurality of elastic wave filters, a series arm resonance unit (304) closest to the common connection terminal has a plurality of elastic wave resonators (304a to 304c) connected in series, and capacitive elements (304d and 304e) connected between a reference terminal and at least one of connection paths between the plurality of elastic wave resonators (304a to 304c).
(FR) La présente invention concerne un multiplexeur (1) comprenant une pluralité de filtres à ondes élastiques connectés à une borne de connexion commune. Dans un filtre côté transmission (13) parmi la pluralité de filtres à ondes élastiques, une unité de résonance de bras en série (304) la plus proche de la borne de connexion commune est dotée d'une pluralité de résonateurs à ondes élastiques (304a à 304c) connectés en série, et d'éléments capacitifs (304d à 304e) connectés entre une borne de référence et au moins l'une des voies de connexion entre la pluralité de résonateurs à ondes élastiques (304a à 304c).
(JA) マルチプレクサ(1)は、共通接続端子に接続された複数の弾性波フィルタを備え、複数の弾性波フィルタのうちの送信側フィルタ(13)において、共通接続端子に最も近い直列腕共振部(304)は、直列に接続された複数の弾性波共振子(304a~304c)と、複数の弾性波共振子(304a~304c)のそれぞれの間の接続経路の少なくとも1つと基準端子との間に接続された容量素子(304dおよび304e)とを有する。
