1. An integrated receiver comprising:

  • a substrate providing a physical medium upon which a receiver circuit is disposed;

    a mixer having its circuit elements disposed upon the substrate for converting a received signal to a first IF;

    a first filter bank having its circuit elements disposed upon the substrate for removing an image distortion from the first IF and removing unwanted channels;

    a first I/Q mixer disposed upon the substrate for converting the first IF to a second IF and rejecting a first IF image distortion;

    a second filter bank having its circuit elements disposed upon the substrate for removing an image distortion and unwanted channels from the second IF; and

    a second I/Q mixer disposed upon the substrate for converting the second IF to a third IF and rejecting a second IF image distortion;

    whereby frequency conversion, channel selectivity and all image rejection are performed on the integrated circuit.
