我们研究了 5 类 UTP（非屏蔽双绞线）双绞线在几百 MHz 频率下的 LCTL（纵向转换传输损耗）和辐射发射特性，并插入了不平衡元件来模拟实际的终端设备。结果可以看出，插入不平衡元件后，由于LCTL的劣化，辐射发射增加。使用四端对网络链矩阵计算的LCTL结果与测量结果非常吻合。辐射发射的计算结果也是使用我们提出的分析方法获得的。
We investigated LCTL (longitudinal conversion transfer loss) and radiated emission characteristics of a twisted pair wire in UTP (unshielded twisted pair)-category 5 for a few hundred MHz, with unbalance elements inserted to imitate an actual terminal equipment. As the result, it can be seen that after inserting unbalance element, radiated emission increased due to deterioration in LCTL. The LCTL results calculated using 4-terminal-pair-network chain matrix agreed well with the measured results. The calculated results of the radiated emissions were also obtained using by our proposed analysis method.
