Surface acoustic wave properties of Ba/sub 2/NaNb/sub 5/O/sub 15/ crystals are investigated in terms of electromechanical coupling coefficient k/sup 2/ 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 Ba/sub 2/NaNb/sub 5/O/sub 15/ 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.
