A reactance filter includes a series branch that connects a signal input to a signal output. At least one parallel branch branches off from the series branch with respect to ground. A parallel resonator is arranged in each parallel branch. Two or more series resonators are connected in series in the series branch. A capacitor is connected in parallel with one of the series resonators in the series branch.
