Claim 0:
1. A predistorter for an electro-optical converter, comprising:
a plurality of low noise RF amplifiers distributed along a transmission line that receive an RF input;
second order intermodulation injection (IM2) circuitry comprising an inductively-degenerated frequency doubler to square and filter IM2 products of the RF input;
a Mach-Zehnder Modulator (MZM); and
feed forward circuitry for injection of IM2 to independently propagate RF intermodulation components with velocity matching to the MZM;
and at least one driver to inject the RF input and RF intermodulation components into the MZM.
