Abstract
This paper presents a FEM/SDA based approach for modeling synchronous one-port resonators. Experimental and calculated responses of one-port LSAW resonators and ladder filters are presented to verify the approach. The devices are fabricated on lithium tantalate and lithium niobate, with various values of aluminum thickness and line/period ratio of electrodes.
