Abstract:
(EN)
A filter (10) has a serial arm resonator (s1) connected to a path connecting an input-output terminal (11m) and an input-output terminal (11n), and has a parallel arm resonator (p1) and a parallel arm resonator (p2) that are connected between the same node (x1) on said path and ground, wherein: the parallel arm resonator (p2) has a resonant frequency higher than that of the parallel arm resonator (p1); the parallel arm resonator (p2) has an anti-resonance frequency higher than that of the parallel arm resonator (p1); the parallel arm resonator (p1) and the parallel arm resonator (p2) each comprise an acoustic wave resonator having an IDT electrode; and the IDT electrode (131) in the parallel arm resonator (p2) has a smaller aspect ratio, which is the ratio of a crossing width of multiple electrode fingers with respect to a logarithm of the multiple electrode fingers, than that of the IDT electrode (121) in the parallel arm resonator (p1).
(FR)
Un filtre (10) comprend un résonateur à bras série (s1) relié à un trajet connectant une borne d'entrée-sortie (11m) et une borne d'entrée-sortie (11n), et comprend un résonateur à bras parallèle (p1) et un résonateur à bras parallèle (p2) qui sont connectés entre le même noeud (x1) sur ledit trajet et le sol, le résonateur à bras parallèle (p2) ayant une fréquence de résonance supérieure à celle du résonateur à bras parallèle (p1); le résonateur à bras parallèle (p2) a une fréquence anti-résonance supérieure à celle du résonateur à bras parallèle (p1); le résonateur à bras parallèle (p1) et le résonateur à bras parallèle (p2) comprenant chacun un résonateur à ondes acoustiques ayant une électrode IDT; et l'électrode IDT (131) dans le résonateur à bras parallèle (p2) a un rapport d'aspect plus petit, qui est le rapport d'une largeur de croisement de multiples doigts d'électrode par rapport à un logarithme des multiples doigts d'électrode, que celle de l'électrode IDT (121) dans le résonateur à bras parallèle (p1).
(JA)
フィルタ(10)は、入出力端子(11m)と入出力端子(11n)とを結ぶ経路上に接続された直列腕共振子(s1)と、当該経路上の同一ノード(x1)とグランドとの間に接続された並列腕共振子(p1)及び並列腕共振子(p2)と、を有し、並列腕共振子(p2)における共振周波数は、並列腕共振子(p1)における共振周波数よりも高く、並列腕共振子(p2)における反共振周波数は、並列腕共振子(p1)における反共振周波数よりも高く、並列腕共振子(p1)及び並列腕共振子(p2)は、IDT電極を有する弾性波共振子からなり、並列腕共振子(p2)におけるIDT電極(131)は、並列腕共振子(p1)におけるIDT電極(121)よりも、複数の電極指の対数に対する複数の電極指の交叉幅の比である縦横比が小さい。
