Dear Friends,
I am designing a LNA with S-parameters of a transistor. After I have designed the circuit I have to adjust its input and output matching, but they affect on each other so badly!!! I mean I adjust input matching at 75 Ohm, after adjusting output matching at 75 Ohm, input matching changes so much and I cannot see output matching at 75 Ohm!!!
What should I do? Is there any way to isolate them?
