Connect an external resistor between pins 2 and 3. Lower resistor values increase the overall gain of the modulator circuit.
VCC (+12V) → pin 11 VEE (-8V) → pin 6 GND → pins 2 & 7
The MC1496 relies on an internal Gilbert cell transistor tree. It multiplies two input signals: the carrier input and the modulating (audio) input.

To simulate and test your Mc1496 circuit: It multiplies two input signals: the carrier input
The is a balanced modulator/demodulator integrated circuit (IC) used for signal processing tasks like amplitude modulation (AM), synchronous detection, and FM detection. In Proteus , you can typically find this component or add it through the following methods: Finding the MC1496 in Proteus
If you only have a symbol but no model, you have a beautiful picture of a chip that does nothing. The MC1496 often falls into this category in default Proteus installations.
It is characterized by an optimum carrier input level, typically a 60 mVrms sinewave, to ensure proper switching of the upper devices without introducing excessive feedthrough.
