hi guys, I manage to optimize the s11 and s22 at the centre freq 4Ghz, but my s21 max gain appears at 2Ghz... what happened?? I using a current reuse technique
series inter stage series resonance..the front end uses a high pass filter..
while simulating, I also felt it is true as u guys said. Is there any theories that you guys can refer to support this ? I need to document the "Why" into facts.. thank you!
Hi guys, I using the current reuse technique for my LNA
i manage to calibrate a relatively good s11 and s22 at my operating freq at approximatley 25db however my s21 appears to be at 13db roughly..which according to journal.. it should be 19-20 db.. or maybe better ..as i got a far more better...
