hi everyone,
When we design a LNA, we alway use available power gain circles. Can we really predict the gain with them? As we konw, Ga is difinited with both ports conjugate matched. If we want simultaneous conjugate matching, we just have one choice. Can we change the source-reflection coefficient, and still use the Ga equation? Thanks in advance.
