ABSTRACT: Dr Jonas Urbonas provides an overview of high-power high-gamma on-wafer hybrid-active waveguide vector receiver load pull at mmW frequencies (50-110 GHz). He starts with explaining the motivation and customer challenges, proceeds to introduce a turnkey solution to solve these challenges, and then provides a quick demonstration of of high-power high-gamma on-wafer hybrid-active waveguide vector receiver load pull at 90 GHz.
