| 摘 要： | 功率放大器是射频前端中的关键部件，宽带是目前功率放大器的主要发展趋势。根据宽带功率放大器的设计原理，采用推挽结构晶体管，前馈线性化技术，传输线变压器和微带混和匹配电路，利用ADS进行仿真设计，成功的设计出一款宽带功率放大器。实现了多倍频程带宽、确保带内增益平坦、驻波小、线性范围和动态范围大。通过仿真和测试，得到较为理想的结果。

| Abstract: | Wide-band is the main trends of development of power amplifier, which is key component of broadband RF front end. Based on the design theory of power amplifier, a wide-band power amplifier was designed successfully by the push-pull transistor, the feedforward technical of linearization, the matching circuits of transmission line transformers and microstrip, and ADS simulation software. It realized Multi-octaves broadband, flat intraband gain, low standing wave ratio, long linear range and dynamic range. By means of simulation and test, perfect results were achieved. |
