摘要

描述了一种能够在直流至18 GHz带宽上抑制60 dB图像的微波光子移频系统。最终的中频频带可以存在于原始射频频率范围内，隔离度为60 dB。该系统允许通过光纤进行天线遥控，并通过使用波分复用技术保持相位相干性。

An ultrawideband image rejecting microwave downconverter using WDM

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.
