A 2024 GHz, fully integrated power amplifier (PA) with on-chip input and output matching is realized in 0.18 μm standard CMOS process. By cascading two cascode stages, the PA achieves 15 dB small signal gain, 10.7% power added efficiency, 16.8 dBm output saturation power and high power density per chip area of 0.137 W/mm2, which is believed to be the highest power density to our knowledge. The whole chip area with pads is 0.35 W/mm 2, which is the smallest one compared to all reported paper.
