Hi all,
Currently i'm designing CMOS PA in cadence tool, my PA response are listed below:
1. S11 at 27Ghz is -17.311 db
2. S22 at 27 Ghz is -15.23 db
3. Unfortunately my S21 response is below 0 db (-19.44db).
I have go thru others researches paper their response for S21 is above 10db. I'm using cascade topology and even after increasing the stage I still couldn't get better S21 response.:-( Any idea how to get better S21 response?
p/s: I did design for 2.4Ghz, and manage to get S21 above 0 db.
