Abstract
A method for frequency conversion within a satellite-based repeater system. An uplink radio frequency signal having a frequency fis received. A first and at least a second local oscillator signal having frequencies fand f, 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 f. 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 f. The generation and mixing of the signals are performed such that:f>fand f, and.
