Fast Procedure for the Nonlinear Analysis of BAW Resonators

2018 IEEE International Ultrasonics Symposium (IUS), 2018
This work presents the development of a Matlab software tool based on a non-iterative method for the nonlinear analysis of Bulk Acoustic Wave (BAW) resonators and filters. The procedure starts with the admittance matrix extraction of the distributed circuit that models a resonator.

MBE‐Grown ScAlN‐on‐Si Films: Enhancing In‐Plane Crystallinity for Extensional Mode BAW Resonators

Advanced Electronic Materials, Volume 11, Issue 18, November 4, 2025.
The achievement of in‐plane single crystallinity and a high piezoelectric modulus in epitaxially grown ScAlN films on AlN‐buffered Si (111) enables extensional mode ScAlN‐on‐Si bulk acoustic wave (BAW) resonators with an ultra‐high Q of ≈97k at 70.28 MHz, resulting in a frequency‐Q product of ≈6.86 × 1012, suitable for emerging wireless technologies ...

Ladder filter based on microelectronic BAW solidly mounted resonators

2017 Dynamics of Systems, Mechanisms and Machines (Dynamics), 2017
The ladder filters based on microelectronic BAW resonators with a Bragg reflector are designed. The BAW resonator represents a piezoelectric transducer based on zinc oxide films with thin-film electrodes of aluminum films and a Bragg reflector consisting of four pairs Mo-Al and one pair Mo-SiO 2 . The ladder filter topology based on the single T-shaped
