Water dielectric coaxial pulse delay-line

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.
