摘要 针对目前UWB信号设计的现状,通过比较与分析,研究了一种基于负阻效应可控的UWB信号产生的微波电路。通过仿真与实验对其进行了验证,该电路能够在100MHz以上的高速码元信号触发下,稳定可靠地产生中心频率在3~5GHz的频段范围内的UWB信号。制作的电路结构简单、体积小、工程实用性强且极易于集成化。 Investigated and analysed to the development of Ultra-Wideband (UWB) signal designing, a low-power UWB signal generator microwave circuit base on negative resistance phenomenon is proposed in this paper. According to simulation and experimentation, UWB signal with centre frequency of 3 - 5GHz could be generated steadily and safely by the circuit under the triggering of high-speed code element signal exceeding 100MHz. Meanwhile, the framework of the circuit is compact and convenience in engineering applications and IC design.
