1. A guided acoustic wave device comprising:
a substrate;
a lithium tantalate layer on the substrate, the lithium tantalate layer having a first thickness and a crystalline orientation defined by (YXl)Θ°; and
a transducer on the lithium tantalate layer, wherein the transducer is an interdigital transducer that comprises a patterned metal layer having a second thickness (h) and a center frequency wavelength (λ); and
wherein the crystalline orientation of the lithium tantalate layer is defined by (YXl)Θ° where
