[IEEE 2018 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom) - Graz, Austria (2018.7.11-2018.7.13)] 2018 International Conference on Broadband Communications for Next Generation Networks and Multimedia Applications (CoBCom) - A Compact Ultra-Wideband Load-Pull Measurement System

摘要： This paper presents an oscilloscope based load pull measurement system for an ultra-wideband ranging chip. Such a system is intended to characterize a chips radio frequency circuits’ behavior under different operating conditions. The gathered measurement results should then be used for the optimization of the chips external circuitry, to reduce power consumption and improve pulse shaping. In this way we want to accomplish longer battery lifetime and higher ranging accuracy. By postprocessing the measurement results the de-embedding of the measurement circuitry is accomplished. Using verification measurements, we validate the performance of the measurement setup and the implemented postprocessing approach.
