Abstract:

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.
