A novel lightly-doped channel approach for linearity improvement of InGaP/InGaAs pseudomorphic high-electron-mobility transistor device was presented. Light doping in the channel region of the conventional δ-doped InGaP/InGaAs PHEMT was adopted to provide a uniform and symmetric electron distribution in the channel region to achieve flat extrinsic transconductance distribution under different gate bias conditions.
