customized square size 10x10mm LiTaO3 LT LiNaO3 LN chips,double side polished LiTaO3 optical glass wafer
Lithium Tantalate LT LiTaO3 crystals Feature
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.
Both lithium niobate and lithium tantalate can be grown with different properties for differing applications, research projects and production methods. For example wafers free of pyroelectric discharge, 4" (100mm), orientation 36° or 42°.
