Abstract
We present a case study applying an S-parameter-based method for characterizing SAM transducers from 20 MHz to 1 GHz. Leveraging the bandwidth and calibration accuracy of vector network analyzers, this approach enables consistent extraction of both electrical impedance and acoustic response. The results demonstrate the method’s value in isolating transducer behavior, supporting system-level integration, and facilitating repeatable, highfrequency performance evaluation in scanning acoustic microscopy.
