RF-people have steep filters at hand to filter any unwanted "harmonics"
(rather additional sidebands) away. So they don't need a linear carrier input.

This brings up an interesting thought again: If one is after a more linear 
RM one could apply a diode-linearization externally to the MC1496. There is a 
linearization network made out ouf a CA3046 shown in Harris AN6077 Figure 6. 
It seems to be similar to the linearization of BA6110 or CA3280.
