SAW filter basics guide designer choices
Abstract
It is pointed out that a common pitfall of the systems engineer seeking a surface acoustic wave (SAW) filter is a tendency to think in terms of the characteristics of other technologies, such as LC filters. However, SAW specifications should be approached as unique. Attention is given to the contribution to SAW filter losses provided by electrical mismatch, the selection of a matching circuit for a SAW filter, the degradation of both passband and stopband performance of the filter by crosstalk, approaches for controlling crosstalk, and transducer configurations for low loss.
