Abstract
An interfering signal canceller for cancelling an interfering signal component of an input signal includes a voltage sensor element disposed in a primary path and fed by the input signal, a coupler disposed in the primary path and fed by the voltage sensor element, a Hartley image-reject element disposed in an auxiliary path and fed by the input signal for converting the input signal to an intermediate or baseband frequency signal, a phase slope compensator disposed in the auxiliary path after the Hartley image-reject element to allow broadband phase adjustment of the interfering signal component of a converted input signal, and an inverse Hartley image-reject element disposed in the auxiliary path after the phase phase slope compensator to convert the passed the interfering signal component to the predetermined band of frequencies and having an output fed to the coupler.
