Abstract

Due to the need of wider bandwidths with the deployment of 5G-NR such as the cases of bands n77 and n79, there is a growing interest in the design of structures combining acoustically-coupled with electrically-coupled resonators. These mixed structures have the advantages of both configurations, having the great selectivity of a ladder topology with electrically coupled resonators, but being less reliant on the pole-zero distance of the resonator impedance to achieve higher bandwidths. Based on the resonances present in a Double-Mode SAW (DMS) resonator, this works presents the equivalent circuital and nodal representations of the DMS for the synthesis of ladder-DMS hybrid structures.
