This paper design and realize 3 bit phase digitizing analog-to-digital converter (ADC) and digital-to-analog converter (DAC) for digital radio frequency memory (DRFM). The instantaneous bandwidth (IBW) of the DRFM is enhanced by high sampling rate. Test results show that the highest sampling rate is 3.4 GS/s and the core power dissipation of ADC and DAC is 350 mW and 300 mW, respectively.
