Water dielectric coaxial pulse delay-line

摘要: 介绍了水介质同轴型方波脉冲延时线的基本原理和基本特性参数，并对延时线传输脉冲的脉冲损耗和脉冲畸变的主要影响因素进行了理论分析。在理论分析的基础上，设计、建立了一套延迟500 ns、阻抗为12 Ω的水介质同轴线型方波脉冲延时线，并进行了初步的实验研究。实验结果表明:该延时线输入方波脉冲前沿为18 ns，输出方波脉冲前沿增加到26 ns；方波脉冲幅度损耗率为9.6%；延迟时间为476 ns。

Abstract: The basic principle and characteristic parameter of water dielectric coaxial pulse delay-line are introduced, and the main reasons of pulse losses and pulse distortion in the process of pulse transmission are analyzed. A test equipment of water dielectric coaxial pulse delay-line has been built, and its characteristic impedance is 12 Ω. The elementary test results indicate a pulse loss rate of 9.6% and a delay time of 476 ns.
