Hello my friends, I'm new here and I hope someone may can help with this mixer.
I'm trying to do a synchonous demodulator, and multplying the AM signal with the local carrier I'm hope that the carrier frequency does not appear in the result of this multiplication. The expected would be that the information would appear in the baseband and the other harmonic component would be around twice the frequency of the carrier. I'm using a single JFET mixer (in the atached file) and the frequency component of the carrier ALWAYS appear in the Vout. Please can someone help me, I'm just trying to understand why this happened. Thank you!
