Modified Loss Mechanism of Mason Model for Bulk Acoustic Wave Resonators

Qingwen Li et al.

Summary: The frequency-adaptive loss mechanism of the Mason model, which incorporates intrinsic loss factors of piezoelectric material and modifies the values of loss components to be frequency-adaptive, improves the simulation accuracy of BAW resonators. Simulation results demonstrate that, without considering transverse effects, the Mason model and the 2D model based on FEM show good agreement across the full-frequency range.
