Abstract
A filter may include a substrate and a rotated YX-cut piezoelectric plate coupled to the substrate. The filter also may include an interdigital transducer (IDT) formed on a portion of the rotated YX-cut piezoelectric plate forming a diaphragm that spans a cavity between the rotated YX-cut piezoelectric plate and the substrate. The IDT includes interleaved fingers that are disposed on the diaphragm. The IDT has an aperture that is less than or equal to 4 times a pitch of the interleaved fingers.
