Description
Lithium Tantalate (LT, LiTaO3) has unique properties, which as a material finds uses in Electro-Optical and Acousto-Optical applications. These can besurface 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°.
