Abstract
In this paper, we proposed a mixed-mode s-parameter measurement system for measuring the performance of twisted pairs. A twisted pair is a balanced type component, its characteristics can not be directly measured using network analyzer, which is generally implemented as a unbalanced type. It is possible to convert between balanced signal and unbalanced signal by using a balun but it restricts the frequency range of the measurement system. The proposed system measures the performance of twisted pairs by measuring mixed-mode s-parameters using a 4-port vector network analyzer and a designed fixture, without using a balun. We measured the performance of a commercial Ethernet cable and compared with the results which measured by using baluns. The results showed that the proposed system is capable of measuring the performance of twisted pairs.
