Patent number: 8862087Abstract: A method for reciprocal-mixing noise cancellation may include receiving, from a first mixer, a first signal comprising a wanted signal at a first frequency and a modulated signal at a second frequency. The modulated signal may be a product of a reciprocal-mixing of an unwanted signal with a phase noise. One or more portions of the modulated signal may overlap the wanted signal, adding a reciprocal-mixing noise to the wanted signal. A second signal may be generated by mixing, at a second mixer, the first signal with a third signal, which is at a third frequency related to a blocker offset frequency. A gain may be applied to the second signal to generate an amplified second signal that may be subtracted from the first signal to generate a fourth signal.
