Abstract :
In this paper, a performance-enhanced ultrawideband monocycle pulse generator circuit using a step recovery diode is designed and tested. Factors that could cause pulse waveform distortions are analyzed. By applying an attenuator and a simple yet effective pulse-shaping circuit, the impedance matching between the pulse generator and the oscillator source is considerably improved, and a quality monocycle pulse is generated with small ringing and leveraged amplitude. Measured results validate the design.
