摘要
针对射频功率放大器仿真设计中的问题,利用ADS仿真软件设计一个功率放大器仿真模型。在仿真设计中选择合适的晶体管模型,并采用负载牵引技术找到最佳匹配阻抗值完成匹配电路。仿真模型输出结果显示,在1.9GHz处输出功率为35 d Bm,增益附加效率约为60%,验证了该仿真模型的正确合理性。
A power amplifier base on ADS is developed for the design of the RF power amplifiers. This circuit is designed using a transistor model; the optimal load impedance is selected by load pull simulations to determine the matching networks. The simulation shows a PAE = 60% and a Pout = 35 d Bm at 1. 9 GHz,indicating the simulation model is correct and reasonable.
