mm-Wave CMOS PAs for 5G Handsets

This talk covers basics of mm-wave PA design in CMOS technology for handset phased arrays, targeting the 5G new radio (NR) cellular communication standard. Key PA figures of merit, as well as application of beamforming to combine power over the air are reviewed. Then, starting from practical handset form factor constraints and system-level drivers, CMOS-specific technological and design-related challenges are conceptually illustrated. A survey of the state-of-the-art is presented to give examples of challenges and illustrate PA techniques used to tackle them in linear mm-wave CMOS PAs for 5G NR handsets.
