| Abstract: | Digital IF system is the core part of software defined radio(SDR) platform,which has high requirements on A/D,D/A performance.According to the software defined radio SCA specifications,through detailed analysis of the devices selection,parameter setting,filter design and other key parts,a digital IF system based on the existing baseband system is designed,mainly included AD6645 completing analog-to-digital conversion(ADC),AD9772A completing digital-to-analog conversion(DAC) and a special clock chip CDCM7005 providing clock for each section.The digital IF system using FPGA as a bridge,uniformly managed by DSP management system,with full programmability,allows loading different software for different to achieve different function. |
