Abstract
We report on the DC,the mall ignal and the RF power performance of AlGaN/GaN HFET grown on emi in ulating (.i.)SiC ubstrate.DC characterization how a record transconductance of 300mS/mm for a device ith a gatelength of 0.3 µm.Load pull measurements at 10 GHz were performed,indicating output power levels above 4Watts cw for a unpas ivated 1.6mm device.Finally,tandard equivalent circuit parameter are extracted and verified for devices with different gatewidths.
