Abstract:
The aim according to the invention is to suppress a disturbing SH mode in a ladder-type filter. This aim is achieved in that the resonance frequency of the series resonator responsible therefor is moved and, at the same time, the pole zero distance of the series resonator is reduced by parallel connection with a capacitor. The antiresonance of the series resonator and therefore also the passband thus remain unchanged.

Claim (Index 1):
SAW filter\n comprising\n a series branch, which is connected between the filter input and output and in which series resonators (RS) are arranged, and \n n parallel branches connected in parallel to the series branch and connected to a fixed potential, in each of which a parallel resonator is arranged, wherein 2\u2264n\u22645,\n in which a first series resonator (S x ) is formed with the lowest anti-resonance frequency and the largest finger period of all the series resonators, \n in which the pole zero distance of the first series resonator compared to the other series resonators is reduced to the point that a parasitic shear mode of the acoustic wave is shifted out of the passband of the filter, \n in which the remaining series resonators have a pole zero distance and a finger period, which are greater than in the first series resonator.
