Abstract:
1. 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: an adder operable to combine the products generated by the plurality of mixing circuits to provide an output signal.
