Abstract :
There were difficulties in testing group delay of frequency-translating devices. With the integration of SMC+PHASE calibration method of VNA, we overcome the difficulties and provide a solution for automatic delay measurement of long-length frequency-translating RF links. Finally, the detailed system and flow designs are discussed and the measurement result is analyzed. The overall accuracy of the typical link in this paper is estimated to be 0.18ns.
