(57) Abstract The invention concerns a surface-wave filter in which the acoustic wavepath is reflected in order to reduce the substrate size necessary. The reflections are chosen so that interference due to temperature effects is excluded. The use of filters of this kind as partial filters in a combined filter enables cross-talk to be further reduced.
