Abstract: In this paper, the degradation of a GaN-on-Si based RF power amplifier is investigated by means of electrical characterization. The reliability issues identified during this work are clearly related to the high thermal resistance between the device and the heat sink, which causes gate-leakage current and output power degradation. Moreover, we have demonstrated a low cost thermal optimization approach by increasing the thermal dissipation area and reducing the device carrier thickness. Measurement results show that the saturated output power can be increased from 1 W up to 5 W without device degradation at 3.8 GHz. (C) 2011 Elsevier Ltd. All rights reserved.
