Hi guys please I am trying to simulate an envelope detector on LTspice but I don't seem to be getting it right, please can anyone help me out with a good envelope detector circuit that is easily simulated on Ltspice.

Regards

The simplest envelop detector is a half wave rectifier with a capacitor used in power supplies. Scale that for the frequency you want to use with an appropriate diode and capacitor and you have your envelope detector.

Since I am not well schooled on LT SpticeI would either use the approach of using a predefined PLL model (if one can be found) or more typically, make a PLL out of the parts in the library.
