This paper gives an overview of several design issues for CMOS Power Amplifiers (PA) for wireless and mobile communications. The challenges, faced by the RF PA designer, and the different trade-offs, encountered during the design process, are clearly indicated. The idea of power combining is introduced and it is clarified how this technique can alleviate some of the problems related to the aggressive CMOS scaling. The theory is clarified by several design examples that cover a frequency range from the lower GHz as high as 60 GHz.
