In this paper, an integrated reconfigurable electronic system based on microwave photonics technology is proposed to solve the problems that the integrated electronic system must have the ability to process signals in broadband and multi-bands. The microwave photonics mixer technology is adopted to realize the Up-conversion and down-conversion of the broadband and multi-band RF signal in optical domain, the microwave photonics switching technology is used to achieve channel multiplexing. The system has the parallel processing capability of four channels and can be dynamically reconstructed through the software configuration.
