Description
Summary: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 2.5 GHz transmitting frequency. The designed power amplifier exhibits 19.8 dBm of 1-dB compression point, 24.1 dBm of output power, 35% power-added-efficiency (PAE), and 23.3 dB of power gain under 3.3V and 1.8V supply voltages. The power consumption is about 827.34 mW. A small chip size of 0.81 × 0.65 mm 2 is achieved with all matching networks.
