This paper proposes a 2.4 GHz RF CMOS Power amplifier and variation in its main performance parameters i.e, output power, S-parameters and power added efficiency with respect to change in supply voltage and size of the power stage transistor. The supply voltage was varied form 1 V to 5 V and the range of output power at 1dB compression point was found to be from 10.684 dBm to 25.08 dBm respectively. The range of PAE is 16.65 % to 48.46 %. The width of the power stage transistor was varied from
