Abstract

Un filtro electromecánico mejorado el cual tiene dos resonadores de salida de modo longitudinal en los que están montados unos transductores piezoeléctricos y varios resonadores de modo torsional de varilla de sección transversal circular, dispuestos en sucesión con sus ejes paralelos, caracterizado porque los dos resonadores de salida (EE, EA) están dispuestos paralelos entre sí y perpendicularmente, por uno de los lados, a los resonadores (R1, R2, R3, R4, R5, R6); porque uno de los resonadores de salida (EE) está acoplados a los resonadores no adyacentes (R2, R4)y al resonador más alejado (R6) mientras que el otro resonador (EA) está acoplado a los otros resonadores no adyacentes (R1, R3, R5) y al resonador más alejado (R6) tocando ambos el punto de tangencia con la circunferencia de sección transversal circular del resonador.
