Abstract
Slanted finger SAW transducers allow one to design wide band filters with excellent characteristics. One of the most interesting modifications of such a filter is the slanted SPUDT. We present an approach to the analysis of such filters based on consistent use of the Y-matrix instead of the conventional P-matrix. Conditions of optimal matching of such SPUDT are obtained and examples of the use of the method developed for the design of wide band SPUDT are shown
