Product Description
Lanthanum Gallium Silicate (Langasite) Piezoelectric Wafers
Lanthanum Gallium Silicate (Langasite-LGS) is an advanced piezoelectric crystal engineered for Bulk Acoustic Wave (BAW) and Surface Acoustic Wave (SAW) devices. This material delivers superior spectroscopic and acoustic performance with exceptional structural stability.
Key Performance Advantages
- Piezoelectric moduli approximately 3x greater than quartz
- Moderately high electro-mechanical coupling coefficient
- Increased bandwidth and reduced insertion loss
- Lower SAW phase velocity enabling smaller device sizes
- Structural stability up to melting point for high-temperature applications
