LiTaO3 Surface Acoustic Wave Single Crystal Wafer For SAW Filter

 

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.

 

 

Application:Lithium tantalate (LT) is used as SAW device which screens electromagnetic waves and only picks up specific frequencies. SAW device is used in mobile communication devices, including auto mobiles and TV and VTR tuners.
