Abstract
An apparatus is disclosed for a surface-acoustic-wave device having an Aluminum Nitride substrate layer. In one aspect, a surface acoustic wave (SAW) includes a substrate layer comprising an Aluminum Nitride (AlN) substrate layer, an electrode structure comprising an interdigital transducer, and a piezoelectric layer disposed between the electrode structure and the substrate layer. In some aspects, the piezoelectric layer is Lithium Niobate or Lithium Tantalate.
