Surface acoustic waves on X-cut LiNbO/sub 3/

Surface acoustic wave (SAW) parameters on X-cut LiNbO
₃
were calculated and measured. For the XY20deg cut, a free-surface SAW velocity, a square of the electromechanical coefficient and a temperature coefficient of frequency are equal to 3727 m/s, 1.6% and -65 ppm/K, respectively. For the XY120deg cut, the above parameters are equal to 3403 m/s, 4.1% and -75.7 ppm/K, respectively. These parameters are compared with that of YZ and 128degYX cuts
