AlGaN/GaN HEMTs on SiC operating at 40 GHz

The operation of AlGaN/GaN HEMTs on SiC in the Ka-band is analyzed with respect to the achievable output power between 35 GHz and 40 GHz. 150 nm gate length AlGaN/GaN HEMTs are investigated by active load-pull measurements. Further, small-signal and noise analysis are performed with regard to the use at Ka-band and robust receiver applications.
