Product Description
2-Inch Diameter 0.5mm Thick Langasite Single Crystal LGS Substrate
Lanthanum gallium silicate (La3Ga5SiO14) represents a significant advancement in crystal technology. Originally developed for laser applications, langasite has demonstrated exceptional piezoelectric properties, making it ideal for radio frequency devices. LGS crystals are primarily used in SAW filters and SAW resonators, offering superior performance for high-efficiency broadband frequency applications.
Key Advantages
- Exceptional frequency-temperature characteristics
- High electromechanical coupling coefficient (3-4 times greater than quartz)
- Unparalleled Q-factor performance
- High thermal stability and low equivalent series resistance
- Excellent physical and chemical stability
