Hi everyone....
I am new to RF circuit design, and received my first task to design an LNA.
There is this question asking:
1. What will happen when the LNA receives a large interference signal (equivalent to 1dB compression point)? What is the effect on Noise Figure and S11?
2. What is the effect of changing the output impedance to 200 Ohm(from 50 Ohm initially) on S21 and the voltage gain of LNA?
I have tried to read some books by Razavi and Thomas Lee, but could not find some proper and good explanation.
Please kindly help me.... I am really in need of help to complete the project which will due next week.....
Thank you for your help.
