Abstract
A controllable apparatus for providing a compensated RF signal including an input port for coupling with an RF signal source, such as a multifrequency CATV signal, and an output port for coupling to an associated electronic device. The controllable apparatus generates new second and third order products from the multifrequency RF signal which are the same magnitude, but opposite in phase to the nonlinear products generated by the electronic device. Since both the original multifrequency RF input signal and the new generated products from the distortion control circuit are coupled to the electronic device, the nonlinear products from the distortion control circuit and the electronic device will be canceled and the output of the electronic device will comprise only the multifrequency RF signal. The controllable apparatus includes an RF circuit path and a controllable nonlinear compensator transversely connected to the RF circuit path. A control bias input allows selective control of the nonlinear compensator.
