Abstract :
This paper describes a general method for the synthesis of SAW filters based on the composition of basic structure elements and variation of electrode lengths. Optimization algorithm using the scanning window approach allows effective synthesis or improvement of responses for different types of filters. The realizability and adequacy of the synthesis results were improved because the topology constraints and stray elements under simulations were accounted for. The two-dimensional grid method was utilized to develop DMS and RSPUDT filters, including filters on langasite.
