Abstract :
A microwave-photonic frequency shifting system capable of 60 dB image rejection over a DC to 18 GHz bandwidth is described. The final IF band can exist within the original RF frequency range with 60 dB isolation. The system allows antenna remoting via optical fiber, and maintains phase coherence through the use of WDM techniques
