如果你要取得 IIP3>-5dBm 的性能,一般都需要degen 电感.还有一些非线性相消的方法可以取得IIP3>+5dBm.

make sure your DC operation point is reasonable (both Vgs and Vds have some margin for the input device working safely in saturation region). -20 dBm is too low, so there may be some fundamental aspects in your circuit being overlooked.
