A MULTI-BANDWIDTH SAW FILTER

摘要

A multi-bandwidth SAW filter (405) for an input signal (90) is provided which in cludes a SAW transducer (402) having a selectable length to corresponding to the desired bandwidth of the filter. The SAW filter i s 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.
