Answered: How Many IF stages in the receiver?


In an online article I just read, when the author described RC receivers he split them into two groups; those (Heterodyne Receivers) that demodulate RF signals down to the receiver’s baseband in one stage (using a 455KHz IF) and those (Supreheterodyne Receivers) that demodulate the signal in two stages (using a 10.7 MHz IF and a 455 KHz IF).

I am curious if you can tell me whether the Vex receiver is an instance of either of these types (and if it’s IF frequency(s) matches the one(s) named in the article).


The Vex Receiver is a double conversion superheterodyne receiver, much like an FM radio.
