Prof. Hua Wang of ETH, Zurich

This talk presents a focused overview of mm-wave power-amplifier (PA)
designs in silicon, including design fundamentals, advanced PA
architectures, and state-of-the-art design examples. The talk will start
with an introduction of PA performance metrics and their impacts on
wireless systems. Next, it presents the design fundamentals of PA active
devices and passive networks as well as power combining strategies.

The tutorial discusses advanced PA architectures, including Doherty,
Outphasing, and Hybrid PAs, for high efficiency, linearity, and bandwidth.
Further, advance and challenges of high mm-Wave PAs will be covered to
address the emerging beyond-5G/6G applications. Finally, the talk will
conclude with several state-of-the-art mm-wave PA design examples.
