Abstract

High power density Al_0.3Ga_0.7AS/In_0.15Ga_0.85As doped-channel FETs (modified DCFETs) biased at 3V for 2.4GHz wireless communication applications are proposed. A planar Si δ-doped layer is inserted inside the wide-bandgap undoped AlGaAs layer to reduce parasitic resistances and enhance the device microwave power performance. The modified DCFETs (M-DCFETs) exhibit an output power density of 302mW/mm, a power-added efficiency of 52%, and a linear power gain of 19dB under 2.4GHz operation for a 1 mm gate-width device. These characteristics suggest that doped-channel FETs with a planar Si δ-doped layer can be used in high linearity and high power microwave device applications.
