Description
technical field [0001] The invention belongs to the field of optical signal processing and integrated microwave photonics, in particular to a reconfigurable integrated microwave photonic radio frequency front-end device. Background technique [0002] With the capacity requirements of the communication system and the continuous expansion of future services, the RF front-end needs to have the ability to process high-frequency, multi-band broadband signals, and flexible reconfigurable capabilities. However, the electronic devices used in the traditional RF front-end are obviously insufficient in processing high-frequency and broadband signals, and cannot solve the multi-channel, multi-band, and multi-functional requirements. How to solve the problems caused by traditional microwave technology and provide a high-performance integrated RF front-end, microwave photonic technology provides a new idea to solve this problem. [0003] Microwave photonic technology is an interdiscipli...
