| 摘要: |
| 本文将给出绝对有源二端口网络S参数的存在范围。这个存在范围的边界是针对|S_(22)|,|S_(11)|平面内,散射矩阵元S_(11)和S_(22)的模的大小给出的。研究表明:在已给出S参数四个模中的三个和四个幅角的情况下,绝对有源条件通常给出散射参数的第四个模的上、下限。在文章的最后将给出一些简单的例子,以说明理论结果的有效性。 |

| Abstract: |
| In this paper the existence range of the scattering parameters of unconditional ac-tive two-ports are presented. The limits to the moduli of the elements S_(11) and S_(22) of the moduli ofthe scattering matrix are analysed in the |S_(22)|, |S_(11)|--plane. It is shown that the condition of un-conditional activity in general produces upper and lower bounds to one of the four moduli of thescattering parameters, if the moduli of the remaining three elements and all four angles of the ele-ments are given. The vality of the theoretical results are established by some modest examples. |
