Simulation of Balanced Surface Acoustic Wave (SAW) Devices Incorporating a Modified Four-port Mason’s Equivalent Circuit Model
نویسنده
چکیده
In the present work, a four-port model for inter-digital transducer was developed. This model was modified from Mason’s equivalent circuit and was ideal for the simulation of balanced mode surface acoustic wave devices. Inheriting the virtues of Mason’s model, this model included the energy storage effect and was capable to fit arbitrary polarity configuration of transducers. Simulation results for an unbalanced-balanced longitudinal coupled double mode SAW filter compared well, the experimental results showed, validating the proposed model. Key-Words: Surface acoustic wave, Equivalent circuit model, Balanced longitudinal coupled double mode SAW filter.
