Abstract :
A new cut of quartz for SAW devices was discovered by a leaky surface-wave mode. The temperature stability is extremely high and experimental temperature dependence of the phase delay change is within ±10 parts in 106 for the range from ¿20 to 80°C. The propagation loss is only 2.6×10¿4 dB/¿.
