– In this paper, we describe the design and implementation of a CMOS WiMAX Power Amplifier implemented using a two-stage cascade topology. Multiple stages have been combined utilizing power-combination transformer techniques. Simulation results show a power gain of 29 dB with a P1dB of 30.71 dBm and an EVM of 3% @ 23.5 dBm with a PAE of 21.5%. ................
