In this letter theoretical calculations and experimental results of ultrasonic generation and detection up to 800 MHz using an acoustic superlattice of LiNbO3 crystals are reported. The experiment is in good agreement with theory. Transducers with an insertion loss of nearly 0 dB at 555 MHz and a 5.8% 3 dB bandwidth have been made.
