Summary :

Fine adjustment of wide-bandwidth SAW filter responses by trimming the interdigital transducer finger lengths was successfully achieved. In SAW devices, second-order effects, such as end effects, diffraction and bulk mode generation, disturb the simple design performances. The slight difference in wide-bandwidth frequency responses between the theoretical and experimental responses was modified by trimming the IDT finger lengths by hand.
