I am new in RF design. I want to design a class A power amplifier at 850 MHz by ADS. How to calculate Zin and Zout of transistor Q2SC5761_M16 for input and output matching network. Hfe of transistor Q2SC5761_M16 and QN3440 are 300 & 100 respectively.
Graph of Vce Vs ic is correct but graphs of Zin and Zout are wrong.

You just use ADS match tools to do that, it is easy. If you need more help. check the textbook.
