摘要： The present invention provides a single-stage tunable Ultra-Wideband (UWB) pulse generator, by creating and differentiating a variable edge rate signal. Edge rate variability is introduced by first applying a step recovery diode (SRD) to compress the edges of the source and then applying a simple RC network to adjust the edge rate. Next, the resulting signal is differentiated using microstrip transmission lines. The tunable generator resulting from this approach demonstrates a Gaussian and monocycle pulses with good symmetry and low distortion over the tunable range.

摘要： A pulse generator utilizes a pair of current sources acting through a pair of Schottky diode switches to provide load currents in opposite directions through a load resistor to produce an output voltage across the load resistor of magnitude proportional to the difference between the load current magnitudes. The pulse generator output voltage is abruptly driven to zero potential by applying balanced, rapid slewing voltage pulses to the Schottky diode switches, causing the switches to simultaneously divert the load currents from the load resistor. The balanced voltage pulses are developed at the terminals of a step-recovery diode by switching the step-recovery diode from forward to reverse bias state.
摘要翻译：脉冲发生器利用通过一对肖特基二极管开关作用的一对电流源，通过负载电阻器在相反方向提供负载电流，以在负载电阻器两端产生与负载电流幅度之差成比例的大小的输出电压。通过将平衡的快速回转电压脉冲施加到肖特基二极管开关，使脉冲发生器输出电压突然驱动到零电位，使开关同时转移负载电阻的负载电流。通过将升压二极管从正向切换到反向偏置状态，平衡电压脉冲在阶跃恢复二极管的端子处产生。

摘要： A series connected electronic circuit including in combination a trigger generator, an impulse generator, a filter circuit having an inductance L, a step recovery diode having a forward resistance RF and a reverse capacitance CR and an optimal bias circuit coupled to the step recovery diode. The trigger generator produces a train of pulses having a relatively long time interval, T, between each pulse; these pulses are then coupled to the impulse generator which produces an impulse having a Fourier component predominant at a frequency omega in response to each trigger pulse. The filter circuit converts each impulse into a damped sine wave having an angular frequency omega and a damping constant delta RF/2L. The sine wave is coupled to the step recovery diode which generates a single high voltage subnanosecond pulse having a half period, tp/ pi square root LCR in response to each damped sine wave.
