Abstract

Long Term Evolution (LTE) communications systems are increasingly used for remote applications where a battery life of at least ten years is often required. Numerous technologies have been proposed to increase the efficiency of this standard, particularly the power amplifier, however these tend to involve resource intensive signal processing, together with a higher component count. This paper presents the use of a low speed load pull technique, with and without a dynamic power supply system in order to optimise performance. This system was tested with LTE signals and appropriate hardware, providing up to 44% increase in power-added efficiency for the fixed supply voltage case and a 27% increase over basic dynamic power supply architectures whilst maintaining ACLR and EVM performance.
