Title:
ACOUSTIC WAVE DEVICE AND LADDER TYPE FILTER
Document Type and Number:
WIPO Patent Application WO/2018/030170
Kind Code:
A1
Abstract:
Provided is an acoustic wave device which is capable of enhancing power resistance. An acoustic wave device 1 wherein first to third surface acoustic wave resonators S1-1 to S1-3 are connected in series so that the first surface acoustic wave resonator S1-1 is arranged on one side of the second surface acoustic wave resonator S1-2, while the third surface acoustic wave resonator S1-3 is arranged on the other side. With respect to the first to third surface acoustic wave resonators S1-1 to S1-3, a first common bus bar 22 is connected to a reflector 14, 16 of one of the first and second surface acoustic wave resonators S1-1, S1-2, and a second common bus bar 25 is connected to a reflector 17, 19 of one of the second and third surface acoustic wave resonators S1-2, S1-3.
