Design of Ultra Wideband Digital Receiver Based on RFSoC
With the development direction of miniaturization、intelligence and multifunctionality for modern radar,wideband digital phased-array radar has become an inevitable development trend.In this paper,the structures of wideband digital receiver are intro-duced,the basic principle and development demand of IF-digitize receivers and RF-digitize receivers are also presented.Based on the development of microelectronics and technologies of signal processing,RF direct sampling can be realized.An ultra wideband RF-digitize receiver based on RFSoC is designed and presented.This multi-channel digital receiver can realize 2 GHz instantane-ous bandwidth direct RF sampling and wideband arbitrary waveform generation,the test result of which meets the system require-ments.The design will be widely used in radar and electronic warfare system because of its low-cost and low power consumption.
