A noise suppression method of a wave filter used to eliminate standing wave signal interferences in the acoustic wave filter consisted by a plurality of film bulk acoustic resonators (FBARs). The method is to provide a plurality of scatterers in the structured consisted by the FBARs, thereby creating...http://www.google.fr/patents/US7057476?utm_source=gb-gplus-shareBrevet US7057476 - Noise suppression method for wave filter
