Parametric study of the resonant TC-SAW piston-mode configurations

Paper i proceeding, 2017

Recent trends in RF filter design has brought the necessity to design SAW resonators with boosted performance. Most importantly, improvements in both the resonators' quality factors (Q) and temperature coefficient of frequency (TCF) are needed. TC-SAW concept employing 128 Y-cut LiNbO3 has attracted considerable practical interest in this view. Some excellent works from Qorvo have demonstrated the viability of this technology. Here we present some more detailed theoretical and experimental studies on the scaling rules regarding the design of TC-SAW resonators with suppressed spurious transverse mode responses.
