Langasite (La3Ga5SiO14) Single Crystal Substrate

Product Overview:
Langasite (LGS) crystal belongs to the trigonal system. It possesses excellent high-temperature stability (no phase transition from room temperature up to its melting point), good piezoelectric properties, and low acoustic wave propagation loss. It is widely used in Surface Acoustic Wave (SAW) devices, Bulk Acoustic Wave (BAW) devices, and electro-optic Q-switches.
