Filters That Use Resonators With DMS Can Produce Optimal Results

Designing distributed filters that incorporate resonators with defected microstrip structures (DMSs) can help combat spurious passbands. A new feature in Nuhertz Technologies FilterSolutions program supports the design of filters utilizing DMSs. This article explains how to efficiently design such filters using Microwave Office circuit design software and the new FilterSolutions modeling capability in order to achieve accurate synthesis of stripline, microstrip, or suspended substrate filter designs when using these resonators.
