Dear all
Imagine the folllowing: we have passive antenna which feeds receiver's LNA input without any filter between them. It appears that S21,S12,S22 and NF of LNA are good, but S11 is very poor. I wonder if we would observe any negative effects due to poor LNA matching in such receiver.
Any opinions would be appreciated![Smile :) :)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
