Abstract :
The basic principles of surface acoustic wave (SAW) devices are discussed with specific reference to SAW filters. It is shown how digital filter theory can be applied to the design of SAW filters and a program based on this principle is presented. The effect of diffraction on surface acoustic wave bandpass filters is discussed and a program for the analysis of SAW filter responses including such diffraction is presented. Sample results are given, illustrating the severity of the effect of diffraction in SAW filters
