Abstract:
The invention relates to a circuit operating with bulk acoustic waves with at least electroacoustic systems, each arranged in a branch (Z1, Z2, Z3, Z4), wherein each electroacoustic system comprises at least two series-connected resonators (R11, R12; R21, R22; R31, R32; R41, R42) in the respective branch, which are galvanically separated from one another and acoustically coupled to one another by means of a coupling system (K1, K2, K3, K4) arranged therebetween. The electroacoustic systems are acoustically coupled via their coupling system (K1, K2) and/or electrically coupled to one another.
