  • SPURIOUS-FREE FLEXIBLE FREQUENCY CONVERTER AND A SATELLITE COMMUNICATION REPEATER ARCHITECTURE
    Publication number: 20080318522
    Abstract: A method for frequency conversion within a satellite-based repeater system. An uplink radio frequency signal having a frequency fRF is received. A first and at least a second local oscillator signal having frequencies fL01 and fLO2, respectively, is generated. The uplink signal is mixed at a first frequency conversion stage with the first local oscillator signal to generate an intermediate signal having a frequency fMF. The intermediate signal is mixed at a second frequency conversion stage with the at least second local oscillator signal to generate a downlink signal having a frequency fIF. The generation and mixing of the signals are performed such that: fLO1 and fLO2>fRF and fIF fMF=fLO1?fRF, and fIF=fLO2?fMF.
