Product Description
Introduction :
LGS (Langasite La3Ga5SiO14)belonging to the space group P321, point group 32, is a new piezoelectric material,
The main applications of langasite crystals now are SAW device BAW device and electro-optic Q-switch.
The surface acoustic device is prepared with piezoelectric crystal as the substrate is easy to realize the miniaturization of the device due to its excellent electrical properties, and is widely used in communications, radar, navigation, and so on. In recent years, lanthanum gallium silicate structure crystals have been widely used in surface acoustic waves, bulk surface wave filters, and sensors.
Main Application :
- Electro-optic Q-switch
- SAW device /BAW device
- High-Temperature SAW/BAW Sensor
