A two-stage power amplifier using current multiplexing technology and resistor shunt feedback technology to flatten gain and expand bandwidth is designed in this paper. In this paper, the SMIC 40nm CMOS process is used. The power amplifier proposed works in the 5-13GHz frequency range, providing more than 10dB of the gain at the voltage of 1.0V, and has good input and output matching. The return loss is lower than -30dB. The stability factor Kf is maintained at about 1.1, and Bf is greater than 0. The peak power added efficiency of the power amplifier can reach 24%.
