| Abstract: | In this paper,a digital receiver based on wide IF sampling structure of AD6652 is proposed,improving the flexibility,reconstruction and adaptive of the system.Matrix input is adopted by AD6652 to improve input flexibility and reduce spurious signals generated by cross-connect,which can also polyphase merge after decimation filter depending on the application and increase the bandwidth.The theoretical analysis and simulations show that the system is easy to implement and has excellent performance,simple structure and practical application. |
