摘要

功率放大器是通信系统的重要组成部分，其效率和线性度是关键的性能参数。在本文中，我们提出了一个初步的研究射频反馈系统，旨在提高功率放大器的效率-线性权衡。由于反馈和显著的实际改进，我们在权衡方面展示了非常大的潜在改进。为了充分实现潜在的改进，概述了需要进一步的工作。

Investigation into RF feedback for improving the efficiency-linearity trade-off in power amplifiers

Power amplifiers are important blocks in communication systems and their efficiency and linearity are critical performance parameters. In this paper, we present a preliminary investigation into RF feedback systems designed to improve the efficiency-linearity trade-off for power amplifiers. We demonstrate very large potential improvement in trade-off due to feedback and significant actual improvement. In order to fully realise the potential improvement, further work needed is outlined.
