Abstract
This paper presents the design and simulation of an envelope tracking power amplifier (ET-PA) for 28 GHz LMDS applications. A linearization algorithm is also employed in digital domain in order to reduce the distortion of the system. Simulation shows that proposed ET-PA delivers 19dBm output power with 21dB linear gain. Power added efficiency of this amplifier is more than 41% which shows about 15 percent efficiency enhancement compared to conventional LMDS PAs.
