Lithium Tantalate Wafers (LT/LiTaO3) has been recognized as an ideal substrate material for the RF surface acoustic wave (SAW) filter, a key component within wireless communication devices as mobile phones. Its stability and size make it the preferred option among other piezoelectric materials.
Lithium Tantalate Wafers exhibits unique electro-optical, pyroelectric and piezoelectric properties combined with good mechanical and chemical stability and , wide transparency range and high optical damage threshold. This makes LiTaO3 well-suited for numerous applications including electro-optical modulators, pyroelectric detectors, optical waveguide and SAW substrates, piezoelectric transducers etc.
Lithium tantalate Wafers (LiTaO3), has properties which make it useful for SAW (surface acoustic wave) devices and, to a different specification, for optical use. Wafers can be produced with varying properties, such as “black” wafers free of pyroelectric discharge, 4″ (100mm), orientation 36°, 39°, 42 °, 46°, 48°, X-CUT detailed specifications, or with higher physical strength to withstand processing during manufacture, resulting in higher yields.
