A theoretical and experimental study of waveguide coupled SAW resonator filters
Abstract
The coupling-of-modes (COM) formalism is extended to include coupled transducers and applied to the modelling of surface acoustic wave (SAW) coupled resonator filters. The models do not require the derivation of equivalent circuits and they accommodate finger reflections, electromagnetic feedthrough and external matching circuits. Frequency responses for waveguide-coupled devices are computed and compared to experimental results. Longitudinal …
