MM-Wave Integration and Combinations

This article summarizes the status of millimeterwave CMOS PAs and presents various circuit design techniques. The article shows that millimeter wave CMOS PAs are still a bottleneck for millimeter wave system integration and more circuit design effort has to be devoted for millimeter wave PAs implementation along with the development of the nanometer CMOS technologies. The article also shows that fully integrated millimeter wave CMOS PAs using combining structures will be very important for next-generation millimeter-wave high-speed wireless communication systems.
