继近代自动网络分析仪(ANA)问世以后,又出现了基于所谓六端对器件的、原理上崭新的六端对自动网络分析仪。后者较之前者有无可比拟的优点,但六端口器件的基本组成部件是宽带混合接头(魔 T)。因此本文试图就宽带混合接头的设计原理、精度指标及实施方案进行实质性的论证。 Following the advent of the modern Automatic Network Analyzer (ANA), a new, principle-based six-terminal automatic network analyzer based on the so-called six-terminal pair is emerging. The latter has unparalleled advantages compared to the former, but the basic component of the six-port device is a broadband hybrid connector (Magic T). Therefore, this article attempts to broadband hybrid connector design principles, precision indicators and implementation of substantive demonstration program.
