Product Description

Lithium Tantalate crystal 6inch dia150mm LiTaO3 LT wafer ingot, lithium niobate crystal LiNbO3 substrates wafer for saw
Piezoelectric Crystal Lithium Tantalate LT LiTaO3 crystals
Lithium Tantalate (LT, LiTaO3) has unique properties, which as a material finds uses in Electro-Optical and Acousto-Optical applications. These can be : surface acoustic wave devices, bulk acoustic wave devices, piezo-electric transducers and piezoelectric sensors.The 36° and 42 ° cuts of Lithium Tantalate have shown widespread adoption for the telecommunications mobile phone handset market at frequencies from 800 to 2100 MHz. These orientations show an optimized bandwidth / insertion loss trade off in performance and are dominating the ever expanding mobile handset sales.
