Photonic frequency conversion for wideband RF-to-IF down-conversion and digitization

Abstract

A photonic frequency converter based on optical sideband filtering can be used to produce up- and down-converted signals over a wide range of RF frequencies. The reduction of mixing spurs provides an important advantage over conventional RF mixers for wide-band operation. We demonstrate down-conversion from 5 – 20 GHz to a 100 MHz IF with positive gain and… (More)
