Abstract :
In this paper, the RF performance of dual material gate (DMG) AlGaN/GaN HEMT is investigated using ATLAS device simulator and presented as a high performance RF solution to microwave applications. Simulations result reveal improved RF characteristics of DMG AlGaN/GaN HEMT in comparison to Single Material Gate (SMG) AlGaN/GaN HEMT in terms of higher cut-off frequency, current gain and reduced parasitic capacitances strengthening the idea of using it for HF wireless and RF applications.
