| 摘 要： | 本文描述了微波电路中基于负载牵引技术的WLAN功率放大器的设计方法。笔者采用CMOS工艺设计了两级差分放大电路，并对该差分放大电路进行负载牵引。在此基础上，我们设计了输入输出匹配网络，最后使用ADS软件进行整体仿真。结果表明，在1．8V电源电压下，放大器增益为29dB，1dB压缩点的输出功率为18．3dBm，功率附加效率为16．8％，满足系统指标要求。

| Abstract: | The optimum load point corresponding to the expected power of an amplifier can be found elastically by the use of load-pull technique.In this paper,the design of power amplifier for 5.2GHz WLAN is described based on that technique.The technique is applied to a three-stage differential amplifier,and then the input-output matching network is designed.At last,the global simulation is completed by the software of ADS.The power amplifier operates at 1.8V power supply,with 29dB power gain,18.3dBm out-put power at... |
