A review of recent power amplifier IC

This paper given a brief and concise discussion on latest research of RFIC power amplifier (PA) designs, showing the frontier state-of-the-art developments, and then present our PA designs and some typical newest designs in expertise area with three technologies, a.k.a CMOS, SiGe, and III-V semiconductor. At last, three research hotspots and research trends about on chip PA are summarized and discussed.
