Abstract :
We report on the study of tunable surface acoustic waves (SAW) resonators fabricated on SrTiO3 (STO) substrate. Linear electromechanical coupling (induced “piezoelectric” coupling) is realized through electrostriction effect by applying a strong electric bias field in addition to the small signal electric and mechanical fields. Resonators have been fabricated at 2.2 GHz, showing an interesting tunability for variable bandwith filters or controlled sources.
