Abstract :
The authors report on the DC and power performance of GaInAs/lnP composite channel HEMTs with a 30 Å GaInAs channel. Devices with gate length of 0.15 μm exhibit off-state drain-to-source breakdown voltages of more than 10 V and onstate drain-to-source breakdown voltages of 8 V. Using a 450 μm wide HEMT, an output power of more than 280 mW (0.62 W/mm) has been obtained with power-added efficiency of 46% at 20 GHz
