The MC1496 IC(Integrated Circuit) is modulator/demodulator and mixer that outputs voltage that is the product of modulating signal and the carrier signal. Often we want to simulate how the RF mixer or modulator works with electronics design software such as Proteus. Here it is shown how to make the MC1496 part in Proteus for simulation. Once the simulation part is build one can test various communication RF circuit with it as illustrated in the following tutorials.
To make the MC1496 modulator/demodulator part in proteus first we will make a circuit schematic component and then compile it to library. Then from the library we will search and place the new part onto the schematic. From its properties window we will enable the childsheet and from the datasheet we will make the internal circuit of the modulator/demodulator.
So first create a new schematic component for it as shown below.
The pins name and number should match the pins name/number on the datasheet.
Once you have made the part, compile to library by making it a device.
Provide some name to the new IC part.
The footprint step is optional.
The datasheet pdf location is also optional.
Select the library location to save the part. It is good to save it in USERDVC.
Then you are done with device creation. Now go to library and place it on the schematic.
Right click the MC1496 part and choose properties to edit its properties. In the properties window check the box where it says Attach hierarchy module and click ok.
Again right the MC1496 part and this time click on Goto Child Sheet.
Now a new empty schematic will appear in the childsheet. There draw the following circuit diagram.
The name of the port pins should match the pin names on the component part created earlier. The transistor that I used here is 2N2222 general purpose transistor. This circuit diagram is available on the MC1496 datasheet. This is the internal circuit diagram of the MC1496 Integrated Circuit(IC). If you are interested in using MC1496 in your project see the references link below which will help you to understand how to use it.

Very Good Tutorial Thank you, Can this parts simulate and behave like the real MC1496?
Thanks for your kind comment! It does work nearly like a real MC1496 but remember that no simulation part will exactly behave like a real part as there are so many condition involved like temperature, stray capacitance and stray inductance from various components or breadboard, pcb, component like resistor, capacitor exact etc values and tolorance etc.
How can I put the pins on the Parent Sheet?
see the 2nd picture above, the DEFAULT is the pin which you can put on the parent sheet.
Can I save the part with the child sheet in it so I may be able use it in other projects?
i am not sure i don't think you can save the part with child sheet,
