1. A system for frequency down-converting a modulated carrier signal, comprising:

  • a first switch, a first aperture signal, and a first energy storage element that down-converts said modulated carrier signal according to a first control signal and outputs a down-converted in-phase signal portion of said modulated carrier signal;

    a second switch, a second aperture signal, and a second energy storage element that down-converts said modulated carrier signal according to a second control signal and outputs a down-converted inverted in-phase signal portion of said modulated carrier signal; and

    a first differential amplifier circuit that combines said down-converted in-phase signal portion with said inverted in-phase signal portion and outputs a first channel down-converted differential in-phase signal.
