Hi Max,
Please view the attached image, which reports the maximum unilateral transducer gain from equations computed in QucsStudio using S-parameters as 32.8 dB (equations are also visible). This is because the image of .s2p file I attached was extracted directly from the schematic. The formula given in the technical document reduces to the one that I mentioned in the previous post under the conditions of a unilateral maximum approach to gain. It is also mentioned in chapter – 3 page 230 of Microwave Transistor Amplifier Analysis Design, 2nd Edition by Guillermo Gonzalez.
I am where I started. However, thank you for your prompt response and debug suggestion.
PFA
