1. A circuit for producing a plurality of LO signals for down-converting a plurality of different RF signals operating in different frequency ranges, the circuit comprising:

  • a VCO that produces a VCO output signal that serves as a first LO signal having a first frequency;

    a first frequency translator that receives the VCO output signal and produces a second LO signal having a second frequency that differs from the first frequency; and

    a second frequency translator that receives the VCO output signal and produces a third LO signal having a third frequency that differs from both the first frequency and the second frequency.
