Abstract

In this work, the influence of un-doped GaN cap layer on AlGaN/GaN high electron mobility transistors (HEMTs) has been studied by using DC, pulsed I-V, capacitance-voltage (C-V), and load-pull characterizations. The device without cap layer is found to exhibit smaller dynamic range (Von-Vth) compared to that of the device with cap layer. However, the lower interface trap density in the device without cap layer can lead to higher drain current with different quiescent points, resulting in better RF power and gain at 2.7 GHz.
