Design of wideband digital receiver

Radar receivers currently often use digital receivers that gain many advantages compared with their analog counterparts. But high speed mixing and filtering in wideband digital receivers make it impossible to operate on typical structures. In this paper, three novel structures are proposed which can decrease the data rate and save the hardware resources, and in turn make it feasible to realize wideband receivers on the current ASIC devices. The design example and simulation results verify that the proposed structures are high efficient and easy to be implemented.
