Lithium Tantalate

As Lithium niobate, Lithium Tantalate 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.

 

SAW Applications

 

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.

 

For lower bandwidth, higher selection filters other orientations including the 112° rotated cut have shown great promise and are effectively covering the gap between Quartz (Ultra narrow band) and the 36/42 ° (wideband) models

We now supply wafers free of pyroelectric discharge, 4" (100mm), orientation 36° or 42°
