Abstract
To reduce the capacitive coupling between the input and output transducers of a piezoelectric resonator arrangement having a one-piece construction, one or a plurality of coatings disposed between the two transducers, which coatings serve for defining given resonators, are connected to ground on either one or both sides and, if required, one coating of the input and output transducers is also connected to ground.
