摘要

A high power density and a large voltage swing of Al0.5Ga0.5As/InGaAs enhancement-mode pHEMTs operated under Vds = 3.5 V for L-band application has been developed. In the study, we improve the current density and the gate voltage operation region of the device by increasing the Al mole fraction of AlxGa1-xAs to x = 0.5. The developed 1.0 μm long and 1mm width gate FETs exhibit a Vth = +0.24 V and an Imax of 286 mA/mm. The maximum output power at a 1.9 GHz operation, is 95 mW/mm, with a linear power gain of 18.7 dB, and a power-added efficiency of 60%. These characteristics demonstrate a great potential for E-pHEMTs on the high power microwave device applications.
