介绍了一种新型的超宽带、超短、阶跃恢复二极管单周期脉冲发生器。该脉冲发生器采用一个简单的RC高通滤波器作为微分器，直接产生单周期脉冲。脉冲整形网络采用电阻电路实现UWB匹配和基本消除脉冲振铃，并采用整流和开关二极管进一步抑制振铃。获得了脉宽为300 ps、振铃电平为-17 dB、对称性良好的超短单周期脉冲。计算结果与实测结果吻合较好。
We introduce a new ultra-wideband (UWB), ultra-short, step recovery diode monocycle pulse generator. This pulse generator uses a simple RC high-pass filter as a differentiator to generate the monocycle pulse directly. The pulse-shaping network employs a resistive circuit to achieve UWB matching and substantial removal of the pulse ringing, and rectifying and switching diodes to further suppress the ringing. An ultra-short monocycle pulse of 300-ps pulse duration, -17-dB ringing level, and good symmetry has been demonstrated. Good agreement between the measured and calculated results was achieved.
