The invention relates to a two stage radio frequency power amplifier. The stages are cascaded which include inductive shunt peaking on the first stage and common source with resistive feedback on the second stage. The power amplifier uses optimum number of radio frequency components making design simple and also utilizing minimal area of silicon chip. The power amplifier operates in 3.0-7.0 GHz ultra wide band with the lowest gain ripple of +/-0.3 dB for class AB operation. The cascaded stages without current reusing achieves good input matching, good efficiency, excellent gain flatness over 3.0-7.0 GHz and low direct current consumption.
