This work presents the design and analysis of a 5 W power amplifier (PA)MMIC operating between 25 and 27 GHz. The technology used is the 0.1 μm AlGaN/GaN HEMT process of Fraunhofer IAF. To benchmark its performance around 26GHz two preliminary designs are synthesized and analyzed. The measured results demonstrate for the final MMIC up to 5.2 W of output power associated with 32% of power added efficiency (PAE). A peak PAE of 35% was observed in continuous-wave(CW) operation at a drain supply voltage of 15V.
