hi,
I am designing an LNA .While doing the impedence matching i get very narrow peaks of s11 and s22 .As a result of this s11 and s22 for the centre frequency comes below -10db but the whole bandwidth does not satisfy my requirement of s11 and s22 <-10db.
Can somebody tell me how to slighly broaden the peaks of s11 and s22 through matching network.I mean whether to add L or C in Parallel or series and why?
