Abstract:
This paper discusses the relative importance of the different parasitic effects in multi-transducer SAW filters at UHF frequencies. This is accomplished by using a lumped-element circuit model which links the circuit elements directly to the filter-geometry and enables one to identify the sources of unwanted features in the filter frequency characteristics. Further, the model complexity may be reduced by retaining only those circuit elements that lead to the most severe effects. It is shown how...     »
