摘要：
Between the two acoustic tracks of a SAW filter constructed on the surface of a piezoelectric substrate, a metallic shielding structure is positioned and connected to ground in order to shield two transducers positioned in different tracks. In this way crosstalk within a filter is prevented and the stop-band selection is improved.
