Lanthanum Gallium Silicate ( La2Ga5SiO14 ) Also Know as Langasite or LGS Crystal

Lanthanum gallium silicate ( La2Ga5SiO14 ) is a phenomenal invention. 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 is SAW filters and SAW resonators. Experts agree that LGS is the best choice for high-efficiency broad band frequency devices because it possesses exceptional frequency-temperature characteristics, a very high index of electromechanical coupling and un unparalleled Q-factor.
