Quartz Lithium Tantalate has unique properties, which as a Lithium Niobate material finds uses in ElectroOptical and Acousto Lithium Tantalate Optical applications. These can be : surface acoustic wave devices, bulk acoustic wave devices, piezo Specification Wafers electric transducers and piezoelectric sensors. Standard Pyro Electric Neutral Saw Applications High Physical Strength The 36° and 42 ° cuts of Lithium Tantalate have Properties shown widespread adoption for the telecommunications mobile phone handset market at Langasite frequencies from 800 to 2100 MHz. These orientations Yttrium Vanadate show an optimized bandwidth / insertion loss trade off Gallium Orthophosphate in performance and are dominating the ever Gallium Nitride expanding mobile handset sales. Calcium Fluoride For lower bandwidth, higher selection filters other orientations including the 112° rotated cut have shown great Barium Fluoride promise and are effectively covering the gap between Quartz (Ultra narrow band) and the 36/42 ° (wideband) Lithium Fluoride models. Silicon Carbide Both lithium niobate and lithium tantalate can be grown with different properties for differing applications, Silicon on Sapphire research projects and production methods. For example wafers free of pyroelectric discharge, 4" (100mm), Silicon Windows orientation 36° or 42°. Germanium Other specifications can be provided Magnesium Fluoride Doped wafers: Er:LN, Zn:LN and Fe:LN
