Patent ID: 7945217

Claim:
A configurable frequency conversion device, comprising: an up-converter, which comprises up-converter mixers and is arranged to convert an input transmit signal to an interim transmit signal at an intermediate transmit frequency and to convert the interim transmit signal to an output transmit signal at an output frequency by mixing the input transmit signal using the up-converter mixers; a down-converter, which comprises down-converter mixers and is arranged to convert an input receive signal at an input frequency to an interim receive signal at an intermediate receive frequency and to convert the interim receive signal to an output receive signal by mixing the input receive signal using the down-converter mixers; and Local Oscillator (LO) generation circuitry, which is arranged to generate multiple LO signals having respective LO frequencies and is coupled to drive the up-converter and down-converter mixers with the LO signals, and which is externally configurable to modify one or more of the LO frequencies so as to modify any of the output frequency, the input frequency, and a separation between the output frequency and the input frequency without changing the intermediate receive and transmit frequencies.
