Class F Power Amplifier linearization using lut based predistortion

Student thesis: Master thesis (including HD thesis)

  • CERASANI Umberto
The last two decades have seen an incredible proliferation of wireless devices around the world. As wireless communication systems evolve, service quality and efficiency are of primary importance. The trend towards low power hand held transceivers increases all of these challenges. Class F power amplifiers have the highest efficiency for implementation of power wireless transmitters but present non-linear transfer functions. In order to keep the advantages of Class F power amplifiers without their inherent drawback it is envisaged to implement a correcting unit to linearize their transfer function. A Look-up Table (LUT) was used to implement the correction function.
