Abstract

Mejoras en los filtros electromecánicos constituidas por un filtro que comprende una cierta cantidad de resonadores mecánicamente acoplados que vibran en flexión estando fijado cada uno de los resonadores a una placa base y el conjunto del filtro estando tapado por una cubierta de protección contra deterioros mecánicos y contra el polvo, caracterizado porque entre los resonadores individuales (2) o entre grupos de dos o más de estos resonadores (2) se establecen unos tabiques divisores (6) que eliminan el acoplamiento acústico en bypass o le reducen a un valor despreciable.
