摘要：
An ultrawideband (UWB) monocycle pulse generator with dual resistive loaded shunt stabs is present in this article. The proposed pulse generator consists of a step recovery diode (SRD), a Schottky diode, a pair of resistive loaded stubs, and a pair of short-circuited stabs. By introducing an additional resistive loaded stub between the SRD and the Schottky diode, the ringing tail of the impulse waveform Call be substantially suppressed and the resultant monocycle pulse is well-behaved with very low ringing level. The measurement result demonstrates a monocycle pulse with peak-to-peak amplitude of 550 mV, pulsewidth of 320 ps, ringing level of as low as -22 dB, and good pulse symmetry. This pulse generator is suitable for various UWB applications. (c) 2006 Wiley Periodicals. Inc.
