Abstract

A general design is proposed to meet the miniaturization requirement for coherent transponders with multiple turn-around ratios. The transponder can be realized with a single LO and a single frequency conversion for both directions, by unifying different LOs, sharing TR channels, and expanding the processing bandwidth of digital circuits, which accords with the idea of software defined radio(SDR) and replace the traditional LOs in intermediate frequency(IF) for frequency up or down conversion. This design is convenient for chip integration and channel expanding, and can be utilized as a general platform for similar transceivers.
