Mixed Modeling of a SAW Delay Line using VHDL

To aid in the development of SAW sensors for aerospace applications we have created a model of a SAW delay line using VHDL. The model implements the impulse response method to calculate the frequency response, impedance, and insertion loss. The model includes optimization for the number of finger pairs in the IDTs and for the aperture height. This paper presents the model and the results from the model for a SAW delay line design
