Description

Surface acoustic wave properties of Ba2NaNb5O15 crystals are investigated in terms of electromechanical coupling coefficient k2 and frequency temperature coefficients. A X-rotated cut and a Y-rotated cut are selected for their fair coupling. Experimental verifications on a Union Carbide Ba2NaNb5O15 crystal proved excellent agreement for the coupling (1.2%) and markedly better results than computed for the frequency-temperature coefficient. The best value is measured to be as low as 1.5 ppm/K for <101> cut, (101) propagation
