Thank you so much for the answers and advice.
I have cleared much of my doubts.
Do you know if Gilbert Cell is using Synchronous Detection or the one
with +/-IF?

Hi Jason,

The Gilbert Cell was one of the first linear ICs and useful for
balanced Mod/Demod. What comes with it is strictly your choice
(regarding the question of IF or Synchronous Detection).

It would be simpler if you simply said what you need.
