This paper presents a 0.15μm GaN power amplifier (PA) for 5G applications. The differential two-stage PA contains a high-order interstage matching network for AM-PM distortion compensation without adding any extra active device. The implemented PA achieves a peak power added efficiency (PAEsat) of 25.5% and saturated output power (Psat) of 32.1dBm at 26GHz. The simulation and measurement results show less than 1 degree AM-PM variation up to Psat across a 24GHz to 30GHz frequency band.
