摘要：

A SAW bandpass filter on (YZ) LiNbO//3 with two apodized transducers and a multistrip coupler is compensated in its rejection response from an initial 52 db level to a 64 db level. The compensation is accomplished through a technique that determines filter sensitivity through measurements of change in filter electrical response to perturbations in electrode length.
