Firstly, the system structure and working mechanism of the passive tritium TR tube are described, and the technique to measure the breakdown protective characteristics of passive Tritium TR tubes is given in this paper. Secondly, through the experiment, the relationship among the input power, pulse width, repetitive frequency, leakout pulse power, and pulse width is analyzed. Then, the breakdown protective characteristics of passive TR tubes are obtained. Finally, the reference data for impoving the design of passive TR tube and demonstrating HPM short pulse radar are offered.
