A very simple component which can be used to test modulation/demodulation is the MULTIPLIER component. It can be found in the Sources group and the CONTROL_FUNCTION_BLOCKS family.
I guess you can never find such an ideal component in real life, but its a good place to start prototyping your ideas.
Many semiconductor vendors make analog multipliers and mixers. Have you tried to find these components and their SPICE models?
