Connect the modulating signal to Pin 1 and Pin 4.
is a monolithic balanced modulator/demodulator used in communication systems for tasks like amplitude modulation (AM), double-sideband suppressed carrier (DSB-SC), and frequency mixing. While it is not always available in the standard Proteus library, you can integrate it by downloading external library files or manually building a model. How to Add the MC1496 Library to Proteus
The MC1496 relies on an internal Gilbert cell transistor tree. It multiplies two input signals: the carrier input and the modulating (audio) input.
Locate your Proteus installation folder (usually C:\Program Files (x86)\Labcenter Electronics\Proteus 8 Professional\ ). Open the folder, then the LIBRARY subfolder. Copy and paste your downloaded .LIB and .IDX files here. Restart Proteus for the new library to load. Import Tool Method: Open Proteus and go to Library > Library Manager . Proteus Mc1496 Lib

The MC1496 (manufactured by ON Semiconductor and others) is a widely used analog multiplier. It acts as a balanced mixer, featuring excellent carrier suppression and good gain stability. Key Applications
Recovering the original message signal from a modulated carrier. Connect the modulating signal to Pin 1 and Pin 4
Achieving up to -65 dB suppression at 0.5 MHz, making it ideal for suppressed-carrier applications.
is to download a pre-made library from trusted electronic component repositories.
: The IC requires three external DC bias levels. In Proteus, these must be accurately modeled using voltage sources or resistive dividers to ensure the transistors operate within their linear regions. Pin Configuration How to Add the MC1496 Library to Proteus
Understanding the electrical profile of the hardware ensures accurate configuration of the Proteus schematic symbols and spice subcircuits:
These alternatives often have better support for analog mixed-signal components, making them a valuable option.
