Abstract

SAW properties are currently being investigated for the use of LGN and LGT materials. Current efforts are focused on the measurement of SAW reflectivity and resonator performance. This paper will present recent results of SAW reflectivity for various cuts and propagation directions on LGT and LGN. The measurement procedure and the parameter extraction method for the reflectivity will be discussed. Theoretical predictions of the reflectivity for aluminum electrodes, based on fundamental material parameters, will be compared to experimental measurements for various film thicknesses on differing cut angles and propagation directions. Recently fabricated SAW resonator results will be provided.
