| Abstract: | The merits of the full-solid-state pulser, based on avalanche transistor, are high stability, narrow pulse and short rise-time. In this paper, the effect factors of the stability are analyzed. Some optimizing measures are used to improve the stability, and a high-stability pulser is designed: peak voltage is 1 500 V,pulse width is 1 ns, and the pulse width jitter is less than 1% and the peak voltage jitter is less than 1%. By improving the charging form of pulse circuit,the output pulse with repetition of 60 kHz is realized. |
| Keywords: | avalanche transistor all-solid-state pulser high stability high repetition UWB |
