What is the "right" amplification fator of an IF amp vo/vin ?

Hi all

There is no right answer. It is whatever the receiver requires to do it's job. I can tell you that the total amplification from antenna to audio amplifier is 10-12 orders of magnitude or 100-120 dB. does that help?

 

As a rule of thumb, keep your RF gains to about 10X per stage.

 

Can you tell me wat is the "right" gain of the rf amp ?

The right gain can vary from 5X to 50X.
Depends on the distance and strength of the radio signal.

This difficult design problem led to the development of AGC circuits to level out gain settings across strong and weak stations.
