摘要
文章利用小信号S参数和静态电流-电压曲线对功率放大器进行设计,首先把功率管的小信号S参数制成S2P文件,然后将其导入ADS软件中,在ADS中搭建功率管的输入输出端口匹配电路,按照最大增益目标对整个电路进行优化,最后完成电路的设计。
A power amplifier designing method based on small-signal S parameters and the static I-V curve is presented.Firstly,by means of the ADS software,the small-signal S parameters of the power amplifier are utilized to make the file of S2P for the use of the simulation circuits.Secondly,the model of input and the output matched circuits in ADS software is built to optimize the input and the output circuits according to the maximization gain by using the optimization function in the software.Finally,the whole circuit is optimized to complete the design of the circuits.
