Black 6 Inch 0.2mm Thickness Lithium Tantalate Wafer For SAW Use

 

LiTaO3 Lithium Tantalate (LT) crystal is an important multifunctional crystal material with excellent piezoelectric, ferro-electric, acoustic-optical and electro-opticaleffects.Therefore, it has become a basic functional material in the field of acoustic surface wave (SAW) devices, optical communication, laser, and opto-electronics. 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.

 
Main Advantages:
 
High Curie temperature point
Large Thermal power coefficient
Small dielectric constant
Stable chemical and physical properties
