Abstract:
(EN) This elastic wave device (11) is provided with a common terminal (P1), a first terminal (P2), a second terminal (P3), a first filter (111), a second filter (112), and an inductor (113). The first filter (111) uses a relatively low frequency band as a passband, and is a surface acoustic wave filter that utilizes SH waves. The second filter (112) uses a relatively high frequency band as a passband. The first filter (111) is disposed between a branch point (N) and the first terminal (P2) on a path connecting the common terminal (P1) and the first terminal (P2). The second filter (112) is disposed between the branch point (N) and the second terminal (P3) on a path connecting the common terminal (P1) and the second terminal (P3). The inductor (113) is disposed on a path connecting the branch point (N) and the first filter (111).
(FR) La présente invention porte sur un dispositif à ondes élastiques (11) pourvu d'une borne commune (P1), d'une première borne (P2), d'une deuxième borne (P3), d'un premier filtre (111), d'un deuxième filtre (112) et d'une bobine d'inductance (113). Le premier filtre (111) utilise une bande de fréquence relativement basse comme bande passante, et est un filtre à ondes acoustiques de surface qui utilise des ondes SH. Le deuxième filtre (112) utilise une bande de fréquence relativement haute comme bande passante. Le premier filtre (111) est disposé entre un point de dérivation (N) et la première borne (P2) sur un chemin reliant la borne commune (P1) et la première borne (P2). Le deuxième filtre (112) est disposé entre le point de dérivation (N) et la deuxième borne (P3) sur un chemin reliant la borne commune (P1) et la deuxième borne (P3). La bobine d'inductance (113) est disposée sur un chemin reliant le point de dérivation (N) et le premier filtre (111).
(JA) 弾性波装置(11)は、共通端子(P1)と、第1端子(P2)と、第2端子(P3)と、第1フィルタ(111)と、第2フィルタ(112)と、インダクタ(113)とを備える。第1フィルタ(111)は相対的に低い周波数帯域を通過帯域とするフィルタであり、SH波を利用する弾性表面波フィルタである。第2フィルタ(112)は相対的に高い周波数帯域を通過帯域とするフィルタである。第1フィルタ(111)は、共通端子(P1)と第1端子(P2)とを結ぶ経路上において、分岐点(N)と第1端子(P2)との間に設けられている。第2フィルタ(112)は、共通端子(P1)と第2端子(P3)とを結ぶ経路上において、分岐点(N)と第2端子(P3)との間に設けられている。インダクタ(113)は分岐点(N)と第1フィルタ(111)とを結ぶ経路上に設けられている。
