SummaryWe present a Surface Cavity Wave filter (SCAW) structure. It consists of an acoustic filter presenting multiple poles generated by multiple coupled-cavities located between transducers. This approach yields compact filters similar to Double-Mode-SAW filters but with simpler connection, together with a shape factor and insertion loss at the level of ladder filters.
