Characteristic Impedance Analysis and 2X-Thru De-embedding of Fine Line

This paper introduces the characteristic impedance analysis and 2X-Thru de-embedding method of the fine line. This type of transmission line has a frequency dependent characteristic impedance and a time dependent TDR response. In this paper, two sets of experiments are developed to study impedance. 2X-Thru de-embedding was the top choice for DUT measurements due to its simplicity and accuracy. Acceptable de-embedding results of fine transmission line are attained in the range from 0 to 50 GHz.
