Résumé

This article presents the design and the realization of a 4W reactively-matched Power Amplifier (PA), in GaN MMIC technology operating in the 17-20 GHz band. The design has been oriented to be used with Envelope Tracking (ET) systems. The designed PA for Envelope Tracking (PA-ET) is a two-stage reactively-matched PA and it is based on the use of three power transistors from the UMS GaN GH15 technology. Large signal characterizations with 64 QAM modulation show that PA-ET provides an average dynamic output power () greater than 2 W (33 dBm) associated to an average dynamic Power Added Efficiency () greater than 37 % and an insertion gain () greater than 11 dB in the 17-20 GHz band. The ET improves efficiency performance by 21 points compared to a PA using the same technology with fixed bias.
