Design of a 4GHz Spectrum Analyzer Based on RFSoC

ZHU Zheng;LI Jianzhuang;HUANG Zhihua;Sichuan Institute of Solid-State Circuits,China Electronics Technology Group Co.;  
A design of 4 GHz spectrum analyzer based on RFSoC was introduced.The proposed spectrum analyzer used the sweeping operation.It included RF circuits of sweep oscillator LO1,fixed oscillator LO2,mixing,filtering,and other digital circuits such as DDC,CPU,FLASH,RAM.Sweep frequency control,power level calculating and data communication of LO1 was implemented by CPU.RFSoC could finish the whole sweep frequency and signal processing flow with a small amount of peripheral devices.The spectrum analyzer had the characteristics of simple hardware,flexible function and low power consumption,which benefitted from the successful use of SoC and DDC.
