Fundamentals of RF and mm-Wave Power Amplifier Design by WangHua December 2021

renzhixiong

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. Antenna-PA co-designs are covered as well to achieve on-antenna power combining, active load modulation, and reconfiguration. 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.
