Abstract
The invention relates to a circuit operating with bulk acoustic waves with at least electroacoustic systems, each arranged in a branch (Z, Z, Z, Z), wherein each electroacoustic system comprises at least two series-connected resonators (R, R; R, R; R, R; R, R) in the respective branch, which are galvanically separated from one another and acoustically coupled to one another by means of a coupling system (K, K, K, K) arranged therebetween. The electroacoustic systems are acoustically coupled via their coupling system (K, K) and/or electrically coupled to one another.
