Product Description

Customized Orientation LT Lithium Tantalate LiTaO3 Crystal Substrate Wafer

LT Lithium Tantalate LiTaO3 Crystal Substrate Wafer  

 

Introduction:

 

As a typical multi-functional single crystal material, lithium tantalate (LiTaO3 or LT) exhibits its excellent electro-optical, piezoelectric properties and has now been widely applied to many applications, such as electro-optical modulators, pyroelectric detectors, optical waveguide, piezoelectric transducers and SAW (surface acoustic wave) substrates.

Polished LT wafer is widely used in the manufacturing of resonators, filters, transducers, and other electronic communication devices, especially for its good mechanical and electrical coupling, temperature coefficient, and other comprehensive performance and is used in manufacturing high-frequency acoustic surface wave devices, and applied in many mobile phones, intercom, satellite communication, aerospace, and other communication fields.
