摘要：

This paper discusses a method for measuring frequency-dependent characteristic impedance transmission lines using Time Domain Reflectometry (TDR) measurements with an open, short and load calibration. Conventional characterization methods using a network analyzer require precise information on the structure of the transmission line to extract the characteristic impedance, which can be cumbersome. In TDR measurements, the effect of the load can be removed using time windowing, which can reduce the error in the measurements. The results of TDR measurements have been compared with that of a Network Analyzer to quantify the error in the measurements. Both a lowpass filter and a PCB microstrip line have been characterized using this method.
