Résumé

This letter reports on the first demonstration of microwave power performance at 10 GHz on flexible AlGaN/GaN high-electron-mobility transistor (HEMT). A maximum dc current density of 620 mA/mm at V-GS = 0 V and a peak extrinsic transconductance of 293 mS/mm are obtained for a 2 x 50 x 0.1 mu m(2) flexible device. At V-DS = 5 V, a continuous-wave saturation output power density of 0.42 W/mm is achieved at 10 GHz, and associated with a maximum power-added efficiency of 29.8% and a linear power gain of 15.8 dB. The device exhibits an intrinsic current gain cutoff frequency F-T of 38 GHz and a maximum oscillation frequency F-MAX of 75 GHz. This result demonstrates the capability of flexible GaN-based HEMT for the development of applications requiring mechanical flexibility, high frequency operation, as well as high power performance.
