Hi,

Could someone please let me know the advantages of using an apodized IDT design over "reducing the number of fingers in the IDT" while designing a wideband SAW device ?

If I use the apodized transducer as a receiver of the acoustic wave, from the equivalent circuit model of the IDT, my conclusion is that the short-circuit current obtained will be larger for the same bandwidth for an apodized design over the wideband design using reduced number of finger IDTs. Is my understanding correct?

Thanks,

Rahul Kishor
