In any Quaduature modulator, you have a 'combiner' that combines the I
& Q.  Anyone have an idea of how to implement this in pspice 9.2.3?   I
dont see that part in my library... or am I missing it.

It's just an analog adder.  Try ESUM if you're trying to do it
behaviorally.

I have several quadrature modulators lying around here (at the device
