Very high performance InGaP/InGaAs/GaAs PHEMT will be demonstrated. The fabricated InGaP gated PHEMT device with 0.25×160 μm2 of gate dimension shows a 304 mA/mm of saturation drain current at VGS = 0V, VDS = 2 V and a 320 mS/mm of extrinsic transconductance. Noise figure at 12GHz is measured to be 0.46 dB with a 13 dB associated gain. With such a high gain and low noise, the drain-to-gate breakdown can be as high as 10 V. Standard deviation in the threshold voltage of 22 mV across a 4-inch wafer can be achieved using a highly selective wet recess etching process.
