Abstract:
1. An acoustic wave device comprising: a first acoustic wave resonator, the first acoustic wave resonator being a series resonator connected to a series arm of the acoustic wave device and including a first plurality of electrode fingers, the first acoustic wave resonator having a first tilt angle that is an angle formed between a direction perpendicular to a direction in which the first plurality of electrode fingers of the first acoustic wave resonator extend and a direction along which the first plurality of electrode fingers are arranged, the first tilt angle being within a range of ±1° from a power flow angle at a resonant frequency of the first acoustic wave resonator; and a second acoustic wave resonator including a second plurality of electrode fingers and having a second tilt angle that is an angle formed between a direction perpendicular to a direction in which the second plurality of electrode fingers of the second acoustic wave resonator extend and a direction along which the second plurality of electrode fingers are arranged, the second tilt angle being different from the first tilt angle.
