Abstract: Radiofrequency (RF) frontends and links are the key modules for microwave systems like radar, communication, and electronic warfare. The requirements of new-generation intelligent RF system on broad bandwidth, multi-band spectra and reconfigurability bring new challenges to the development of RF frontends and links. Both RF frontends and RF links assisted by the microwave photonics can provide a very promising solution to address above challenges with advantages of broadband, low loss and immunity to electromagnetic interference. In this paper, a comprehensive overview to the intelligent microwave photonic RF frontends and links is presented, focusing on reconfigurable, multi-channel/channelized transceiver frontends and microwave links featuring large dynamic range, high phase stability and multi-service convergence.
