Abstract :
The design of surface acoustic wave (SAW) devices are a hard work. Computer aided design is used for a huge amount of calculation quantity. The main purpose of this paper is to present a diagram of the appropriate device model design method, and analysis techniques for a SAW computer aided design system, including the design of SAW filter, the calculation method of diffraction and it compensates, the input and output of the data and diagram. The design principle of the software is the filter consisting of one apodized and one unapodized inter digital transducer (EDT). The frequency response including diffraction effects is analyzed based on delta - function model if the Fresnel and parabolic-anisotropy approximation are allowed.
