Hello,
i'm trying to match the input and the output stage of a VHF pre-amplifier using simulation in ADS. When i match the output stage everything is ok but when i try to match the input, the output is no longer matched, the gain drops and the stability factor also drops below unity. I guess there is a interrelation between the input and output matching, so whats the proper way of doing this? i'm not very familiar with this rf engineering.
