Frequency Domain Analysis of a SAW Unit Cell

Application ID: 145281


This model shows that the frequency response, i.e. admittance curve, of the SAW unit cell with IDT is in good agreement with the series resonance & antiresonance frequencies obtained from the eigenfrequency studies in the tutorial Surface Acoustic Wave Velocity Calculations from a Unit Cell.

The model also compares admittance curves from the FEM-simulation and from the modified Butterworth van Dyke (BvD) equivalent circuit. The necessary circuit parameters are provided by the above-mentioned tutorial and two additional studies: a Stationary study to extract the static capacitance and a lossy Eigenfrequency study to extract the Q-factor.
