Abstract
Based on theoretical and experimental investigations further possibility of La3Ga5SiO14 - langasite (LGS) application for BAW resonators is described. Anisotropy of frequency coefficients Nf, temperature- frequency coefficients (TCF), electromechanical coupling coefficients (ks) for these modes of vibration of langasite has been investigated.
