Hi All,
When I am tunning LNA, I met a problem:Because this LNA needs high linearity, I added an inductor between transistor emitter and GND. When I increase the value of inductor,the gain meets such problem.as I increase the input power, the gain firstly become higher and then lower down.The increase range is 5dB. So what's the reason?
Thanks!
