Presented by: Travis Ellis Engineering systems for 112G introduces complex interdependent design challenges. More now than ever system engineers are forced to utilize a closed loop design process. Where 3D full wave simulations are used to validate designs before fabrication. Once fabricated these designs and their channel models must be correlated to measured data. To have clear picture of the results test fixtures must be transparent. Achieving fixture transparency is possible with careful design practices along with a deep understanding of what it takes to create these fixtures.
