Method to Reduce Coupon Lengths for Transmission Line S-parameter Measurements through Elimination of Guided-wave Multiple Reflections
A new approach is proposed to reduce the length requirements for the measurement of transmission line S-parameters in printed circuit boards(PCBs).In addition,the approach improves the accuracy of measurements.We demonstrate that guided-wave multiple reflections of the transmission lines in the signal propagation direction limits use of short transmission lines samples.The elimination of the guided-wave multiple reflections is introduced to overcome the coupon length limit for accurate measurements of transmission lines S-parameters.We introduce implementations of the proposed approach in the time and frequency domains.For time-domain measurements,we do corrections to remove the reflection noise signals from received signals: the first is the waveform manipulation for removing the internal reflections,and the second is the novel manipulation of S-parameters to compensate for reflected and transmitted losses.For native frequency-domain measurements,that manipulation of the S-parameters is used as a de embedding correction method to remove the reflected and transmitted signals contributions from the S-parameters.Simulation results are presented to demonstrate the efficiency and accuracy of the new approach.Results show that the new approach can reduce the minimum length of high-speed transmission lines from 8 inches in traditional industry standards to only 0.5 inch for both 4-port TDR/VNA measurements and 2-port SET2DIL.
