Abstract
A system of and method for reducing or eliminating any unwanted sideband component in the output of a transmitter comprising a quadrature modulator followed by a translational loop. In one implementation, a value representative of the unwanted sideband is derived from a low frequency signal generated within or by the translational loop. In this implementation, the low frequency signal is taken from an input to a VCO within the translational loop.
