Product detector circuit

For SSB, it must be demodulated to recover the audio modulation. The circuit shown in the figure can get the job done well. It uses an LM-1496 double-balanced mixer as a product detector. This detector operates in CW, SSB and DSB signal (all of which need a local oscillator to inject signals). And audio signal can be generated by combining the local oscillator signal and the receiver’s SSB IF signal superheterodyne All of the SSB receivers use certain product detector in the end IF chain, many of which use some similar LM-1496 circuits just shown in the figure.
