  • Abstract
    A SAW bandpass filter on (YZ) LiNbO3 with two apodised 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.
