A circuit for use with bulk acoustic waves includes a first electroacoustic system in a first branch and a second electroacoustic system in a second branch. The first electroacoustic system includes a first resonator and a second resonator that are in series in the first branch, and that are galvanically separated, and acoustically coupled, by a first coupling system. The second electroacoustic system includes a first resonator and a second resonator that are connected in series in the second branch, and that are galvanically separated, and acoustically coupled, by a second coupling system. The first and second electroacoustic systems are acoustically coupled via the first and second coupling systems and/or electrically coupled.
