Patent ID: 8909187

Claim:
A receiver comprising: a polyphase filter coupled to an input of said receiver and operable to generate a plurality of phases of an RF signal received via said input of said receiver; a control signal generator operable to generate a control signal, wherein the control signal comprises a plurality of transitions during a period of a local oscillator signal, wherein each distinct transition in the plurality of transitions corresponds to a phase shift of the local oscillator signal; a plurality of harmonic reject mixers, each of said harmonic reject mixers comprising a plurality of mixing circuits operable to receive one of the plurality of phases of the RF signal received via said input and the control signal, wherein each of the mixing circuits is operable to: generate a product of the one of the plurality of phases of the RF signal received via said input and the control signal, wherein the product is generated according to a distinct transition in the plurality of transitions, and apply a scaling factor to the one of the plurality of phases of the RF signal received via said input according to a sinusoidal function of a phase shift corresponding to the distinct transition in the plurality of transitions; and an adder operable to combine the products generated by the plurality of mixing circuits to provide an output signal.
