为了得到超宽带纳秒级窄脉冲信号,在对UWB脉冲产生方法分析总结的基础上,提出了一种基于数字逻辑器件的简单脉冲产生电路。对实际制做的电路进行了测试,能够得到重复频率为10 MHz,脉冲宽度约为4ns,幅度约为500mV的窄脉冲。该电路成本低,结构简单,易于制作,工程实用性较强。

In view of the existing methods, a kind of UWB signal generator based on the digital logic device is designed to obtain the ultra-wideband （UWB） nano-seconds narrow pulse signal. Practical circuit has been tested, and narrow pulses, in which the repeat frequency is 10 MHz, pulse width is about 4 ns and amplitude is about 500 mV, have already been obtained at the same time. This circuit has low cost, simple structure and is easy to construct, which, as a result, has strong practicability.
