摘要
阐述了线性化功率放大器的发展过程。利用ADS进行Doherty功放的仿真分析,设计了一种多个放大器并联的Doherty功放电路,并与经典的Doherty功放比较效率的高低。研究结果表明,此多级并联Doherty功放电路比传统功率放大器效率要高,并且有电路简单、成本低、工作稳定等优点。
This paper briefly describes the history of the development of the linear power amplifier. The ADS software is used for Doherty power amplifier simulation. A Doherty multiple amplifier connected in parallel is de- signed. The power amplifier is compared with the classic Doherty power amplifier in efficiency. The results show that multistage parallel Doherty power amplifier circuit has the advantages of high efficiency, simple circuit, low cost, and stable performance over the traditional power amplifier.
