This paper demonstrates the design of a radio frequency (RF) class A power amplifiers for WiMAX application using TSMC 0.18µm CMOS technology. A novel two-stage cascode common-source amplifier and a load-pull output matched power amplifier are designed for the WiMAX application of 2.5GHz transmitting frequency. The designed power amplifier exhibits 19.8dBm of 1-dB compression point, 24.1dBm of output power, 35% power-added-efficiency (PAE), and 23.3dB of power gain under 3.3V and 1.8V supply voltages. The power consumption is about 827.34mW. A small chip size of 0.81×0.65 mm 2 is achieved with all matching networks.
