A broadband linear power amplifier for software radio applications

Abstract

This paper discusses a new type of polynomial-based RF predistorter with excellent broadband performance and very low levels of complexity. The technique employed may be designed to operate at any desired centre frequency and therefore has application in the PMR, cellular and satellite areas of communications systems. The technique is compact, very simple and of very low cost, so it will find application in handsets as well as within the base station environment.
