Microresonator-based optical frequency combs are promising devices for photonic channelized receivers, enabling full advantage of multicarriers, large bandwidths, and accelerating the integration process of microwave photonic channelized receivers. School of Electronic Information, University of Electronic Science and Technology of China, Zhongshan Institute, Zhongshan, China 3. 1 Channelized Filtering Receiving Technology Based on Fabry–Perot Filter Future applications require military RF systems that can handle higher frequen- cies and greater bandwidth. However, due to the volume and power consumption of traditional RF devices, real-time, high-precision radio.
