Proteus Mc1496 Lib May 2026

Technical Report: Evaluation of the MC1496 Model in Proteus ISIS

Report ID: PRO-LIB-MC1496-01
Date: [Current Date]
Component: MC1496 (Balanced Modulator/Demodulator)
Software: Proteus Design Suite (ISIS)

Running the Simulation:

• Set the transient analysis for 5 ms (enough to see 5 cycles of the 1 kHz envelope).
• Place a differential probe or a virtual oscilloscope on the output.

Expected Result: If the library model is correct, you should see a DSBSC waveform – a 100 kHz carrier whose amplitude varies sinusoidally at 1 kHz, with a phase inversion at the zero crossing of the modulating signal. If you see a standard AM waveform (carrier always present), your biasing or input levels are off – a good test of the model’s accuracy. Proteus Mc1496 Lib

Common Pitfalls in the "Lib"

If you are struggling to get the MC1496 working in Proteus, the issue is rarely the library—it is the Model Compatibility. Technical Report: Evaluation of the MC1496 Model in

Many SPICE models found online for the MC1496 are designed for PSpice or LTSpice. While Proteus can import these, the syntax for .SUBCKT (sub-circuit) definitions can sometimes conflict with the ISIS Schematic capture. Set the transient analysis for 5 ms (enough

The Solution: If the generic model fails, look for the "MC1496.MOD" text file. In Proteus, right-click the component, select "Edit Properties," and link the SPICE Model file to the component. This forces Proteus to treat the schematic symbol as a mathematical representation rather than a generic placeholder.

Who Should Use It?

• ✅ Students doing an AM modulator lab project (just follow a known biasing schematic).
• ✅ Hobbyists prototyping a simple RF mixer before ordering PCBs.
• ❌ Professional RF engineers designing for production (use Keysight ADS or real silicon).
• ❌ Anyone who refuses to read a datasheet – you’ll hate this library.
