Abstract

This paper presents a 2.4 GHz SiGe Power Amplifier based on envelope tracking (ET) technology for long term evolution (LTE) application, aiming to improve efficiency. The ET consists of envelope detector and envelope modulator. Using linear amplifier assisted switching amplifier to improve the system bandwidth, the proposed technique enhances the PA’s back-off efficiency. The power amplifier is designed in 0.18um SiGe process and simulated with LTE16QAM signal. The simulated peak output power is 30.1 dBm at 2.4 GHz with 42% peak power added efficiency (PAE) and average output power is 24.6 dBm with 24% average PAE.

用于LTE应用的2.4 GHz SiGe包络跟踪功率放大器

为提高长期演进(LTE)应用效率，提出了一种基于包络跟踪(ET)技术的2.4 GHz SiGe功率放大器。ET由包络检测器和包络调制器组成。利用线性放大器辅助开关放大器提高系统带宽，提高扩音器的回退效率。该功率放大器采用0.18um SiGe工艺设计，并采用LTE16QAM信号进行仿真。在2.4 GHz时，模拟峰值输出功率为30.1 dBm，峰值功率附加效率(PAE)为42%，平均输出功率为24.6 dBm，平均PAE为24%。
