With a leg up from partner Nuhertz Technologies, the latest version of AWR’s Microwave Office high-frequency design suite adds Nuhertz Filter synthesis and analysis software. Considered a breakthrough, the addition, called delay equalization with off-axis quadruplet and real zeros, promises to reduce the computation time required to obtain flat group delay response in quadruplet zeros delay equalized lumped element filters from hours to seconds. According to AWR, obtaining flat group delay response to ensure that all frequencies arrive at the same time within a filter's passband is one of the most critical aspects of good filter design and is essential in order to obtain distortion-free performance. Nuhertz Filter provides a direct-synthesis strategy for determining the element values that control low-pass or high-pass quadruplet zeros controlled group delay that reduces computation time while eliminating unnecessary circuit components that result from traditional equalization techniques.
