Title

Non-Iterative Design Of Saw Bandpass Filters

Abstract

A general, non-iterative design technique for low shape factor, transversal filters has been developed. This design technique has direct application to SAW filters since both transducers can be designed simultaneously to meet the required filter specifications. The approach uses the superposition of properly designated eigenfunctions which are represented as a cosine series. The choice of eigenfunctions is dicated by passband ripple and sidelobe level. The superposition of different eigenfunctions is applied to the design of each transducer of the SAW filter. The approach is analytic and non-iterative. In addition, several new window functions have been defined. The basis of the theory and a design example are presented. Experimental results of a SAW filter with a 10% fractional bandwidth and a shape factor of 1.18 is provided for verification.
