Abstract: In this paper, power amplifier operating with center frequency of 947.5 MHz, which can be used for the transmitter in beamforming systems, is proposed. The power amplifier implemented provides high power added efficiency (PAE) of 71.967% and low noise figure (NF) as low as 1.525. The linearity of the power amplifier is improved by using square law and cubic law analog predistortion techniques. The power amplifier is designed and implemented using 0.35 ┬Ám CMOS technology. The power amplifier implemented provides high SNR of 82.723 and the linearity is improved by suppressing the power in the 2nd and 3rd order harmonics.
