Doubly apodized SAW filters
Abstract
The design of a surface acoustic wave filter having two apodized in-line transducers is presented. The positions and weights of the taps in both transducers are obtained simultaneously by considering the finger-by-finger interaction between the two transducers. Two design optimization criteria are compared. A device consisting of two 21-tap transducers with a 10 MHz passband centred at 50 MHz is built on 128° rotated Y-cut LiNbO3 to verify the …
