  • Abstract
    This paper describes the design of resonators using waves guided in a piezoelectric layer located above a Bragg mirror. Such a resonator is suitable for the intermediate frequency (IF) and high frequency (HF) ranges. In the IF (about 600 MHz) band, maximum quality factor is achieved when exploiting the second guided mode (analogous to the S0 Lamb wave). In the HF band (about 2 GHz), a higher order mode (similar to the S1 Lamb wave) provides high coupling factors.
