    About Matching Network Design

    Hello, I think your problem that you ignore the effect of S12,so try to follow the following procedure: 1)calculate the K of the transistor at specified freq., Vce & Ic, if k>1 then your Transistor is unconditionally stable so go through next steps.if not then you have to do another procedure...
