Product Description
High Damage Threshold Piezoelectric Materials LGS Crystals For Saw Device
Langasite - Lanthanum Gallium Silicate, is a piezoelectric crystal. Though langasite was initially developed as a laser crystal, it revealed a remarkable combination of piezoelectric qualities, which opened up new opportunities to use the LGS crystal in radio frequency devices. The main applications of langasite crystals now are SAW filters and SAW resonators.
