Abstract:
(EN) A quadplexer (1) is provided with a filter (12) and a filter (22) having a higher passband frequency than the filter (12). The filter (12) comprises series resonators (121s-125s) arranged on a first route and parallel resonators (121p-124p) arranged on a route connecting the first route and a ground. A direction D connecting the tips of a plurality of electrode fingers constituting the individual resonators intersects an elastic wave propagation direction at a predetermined angle. The series resonator (121s) closet to a shared terminal (Port1) does not comprise first electrode fingers (variant fingers). The other series resonators (122s-125s) comprise first electrode fingers (variant fingers).
(FR) Un quadriplexeur (1) est pourvu d'un filtre (12) et d'un filtre (22) ayant une fréquence de bande passante supérieure à celle du filtre (12). Le filtre (12) comprend des résonateurs en série (121s à 125s) disposés sur un premier itinéraire et des résonateurs parallèles (121p à 124p) disposés sur un itinéraire reliant le premier itinéraire et une masse. Une direction D reliant les pointes d'une pluralité de doigts d'électrode constituant les résonateurs individuels croise une direction de propagation d'onde élastique selon un angle prédéterminé. Le résonateur en série (121s) le plus proche d'une borne partagée (Port1) ne comprend pas de premiers doigts d'électrode (doigts de variante). Les autres résonateurs en série (122s à 125s) comprennent des premiers doigts d'électrode (doigts de variante).
(JA) クワッドプレクサ(1)は、フィルタ(12)と、通過帯域の周波数がフィルタ(12)より高いフィルタ(22)と、を備え、フィルタ(12)は、第1経路上に配置された直列共振子(121s~125s)、及び、第1経路とグランドとを結ぶ経路上に配置された並列共振子(121p~124p)とを有し、各共振子を構成する複数の電極指の先端を結ぶ方向Dは弾性波伝搬方向と所定の角度で交差しており、共通端子(Port1)に最も近い直列共振子(121s)は、第1電極指(異型フィンガ)を含まず、その他の直列共振子(122s~125s)は、第1電極指(異型フィンガ)を含む。
