portions of the IC, improving the input to output frequency response. Our line of reflectionless high pass filters used this approach to achieve high stopband rejection to 40GHz (Figure 7.). Conclusion In this paper, we have presented multiple innovative approaches to extending the useful operating frequency range of traditionally low cost, overmolded plastic packaging technologies. Resulting from over two years of research, and through co-development, multiphysics co-simulation, and refining established methods and techniques, we have developed and produced multiple products for use in mmW applications, including: attenuators, equalizers, splitters and reflectionless filters. These innovations have enabled us to meet mmW performance requirements demanded by the telecommunications, aerospace,

The electrical benefits described herein were obtained without sacrifice to the inherent capabilities and benefits of our overmolded packaging methods, such as preserving the moisture sensitivity Level of packages at MSL1.
