This abstract first appeared for US patent application 18976439 titled 'ACOUSTIC WAVE DEVICE
Original Abstract Submitted
An acoustic wave device includes a first acoustic wave filter, a first conductor portion between the first acoustic wave filter and a second acoustic wave filter and connected to a second functional conductor portion of the second acoustic wave filter. The first acoustic wave filter includes a signal electrode on a second main surface of a first piezoelectric substrate and connected to the first conductor portion, a ground electrode on the second main surface of the first piezoelectric substrate, and a second conductor portion connected to the ground electrode. The ground electrode overlaps a first functional conductor portion and does not overlap the signal electrode in a thickness direction of the first piezoelectric substrate. The second conductor portion is located between first and second main surfaces of the first piezoelectric substrate and spaced apart from the first main surface.
