Summary: | Balanced twisted bifilar transmission lines are often used in high-frequency signal-processing applications, in impedance transformers, signal combiners, and power dividers. To apply these transmission lines and structures based on them in high-frequency circuits and systems, the characteristic impedance of the twisted lines must be known. Once a solution has been found for connecting these balanced lines to the unbalanced ports of standard test equipment, it is possible to use a commercial vector network analyzer (VNA) for accurate measurements of characteristic impedance on balanced twisted bifilar transmission lines. |
