1. A conversion integrated circuit (IC) for RF signals, comprising;

  • a first interface for transmitting or receiving signals in a broadband spectrum;

    sideband selection circuit elements coupled to the first interface for up-conversion or down-conversion of the signals to and from an intermediate frequency (IF);

    a second interface coupled to said circuit elements for receiving and transmitting at the intermediate frequency (IF); and

    an on-chip voltage-controlled oscillator (VCO) coupled to at least one of the circuit elements through one of frequency multiplication or division circuitry for generating a local-oscillator (LO) signal to that circuit element for conversion between the IF frequency and the receive or transmit frequency in the broadband spectrum.
