摘要：
A multi-bandwidth SAW filter (405) for an input signal (90) is provided which includes a SAW transducer (402) having a selectable length corresponding to the desired bandwidth of the filter. The SAW filter is responsive to a control signal (430) which corresponds to a selectable bandwidth of the filter to present the input signal to an appropriate length SAW transducer.
