摘要

The propagation constants of transmission lines were measured from 1-port TDR measurements. Since the TDR measurement is a 1-port measurement, error can be smaller than 2-port measurement techniques. Moreover, the available frequency is determined by the rise time of the TDR step pulse unlike TRL methods. The propagation constant of a lossy transmission line was extracted from DC to 10GHz. Simulation of the lossy transmission line using the extracted propagation constant shows good agreement with TDR measurement, demonstrating the accuracy of the TDR measurement technique.
