【Abstract】 An ultra wide band(UWB) time domain signal source based on avalanche transistors and Marx circuits was designed, which has the characteristics of higher peak voltage, faster rising edge, narrower half-pulse width, higher repetition frequency, longer life, etc. Through the 8-way power combination method, under the premise of lower circuit cost, the problem of output voltage saturation was mitigated, and the output voltage of the signal source was increased. Through the parallel technology of transistors, the life time of the signal source was improved under the condition of high peak voltage output. Finally, the signal source achieves a peak voltage of 10 kV, a rising edge of 183 ps, and a half-pulse width of 750 ps. Under the repetition frequency of 20 kHz, it can work continuously for more than 45 min. This signal source can be well applied in target detection, jamming, attack and material disposal.更多还原
