Parametric model of the BAW resonator phase-noise [PDF]
Ultrasonics, 2011 Excepted for the very short terms the frequency stability of ultra-stable oscillators is mainly limited by the resonator noise. In this work we proposed a parametric model of the bulk acoustic wave (BAW) resonator phase noise based on an equivalent circuit.

High Quality Factor Hybrid SAW/BAW Resonators
2022 Joint Conference of the European Frequency and Time Forum and IEEE International Frequency Control Symposium (EFTF/IFCS), 2022 We report hybrid SAW/BAW resonators based on arrays of AlN/Mo transducers located atop a silicon substrate. Thanks to an optimized fabrication process, these devices exhibit quality factors up to 3,900 and 1,700 respectively for the pseudo-SAW and pseudo-BAW modes, at frequencies close to 600 MHz and 2.9 GHz.
