Surface acoustic wave filter with enhanced edge steepness

在一个具有至少三个串联和/或并联彼此错接的谐振器的SAW滤波器中，如果预先规定多个具有不同的叉指换能器的指间隙的谐振器，则改善了导通范围的边缘陡度。 A surface acoustic wave (SAW) filter having an improved edge steepness includes at least three resonators connected in series and/or parallel with one another. An edge steepness of a pass band is improved if a plurality of re...

Zusammenfassung:	在一个具有至少三个串联和/或并联彼此错接的谐振器的SAW滤波器中，如果预先规定多个具有不同的叉指换能器的指间隙的谐振器，则改善了导通范围的边缘陡度。 A surface acoustic wave (SAW) filter having an improved edge steepness includes at least three resonators connected in series and/or parallel with one another. An edge steepness of a pass band is improved if a plurality of resonators with different finger periodicities of interdigital transducers are provided.
