Title:
ELASTIC WAVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2019/065619
Kind Code:
A1
Abstract:
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).
