摘要： 为了满足超宽带混沌通信系统对混沌信号源的要求，提出了一种新型两级超宽带混沌电路的设计，有效地提升了混沌信号的带宽.与经典的考毕兹混沌电路的结构相比，新型结构采用带有集电极电感的射极输出器作为信号输出端，引入高频谐振网络，补偿高频处信号功率谱密度，拓展频带宽度.通过MATLAB软件求解新型两级超宽带混沌电路的数值解，得到新型超宽带混沌电路的分叉图、相图；仿真分析得到电路输出的时域图、频谱图.结果表明：新型两级超宽带混沌电路可产生功率差在20 dB内、带宽约为7.5 GHz的宽带混沌信号，满足超宽带信号指标（3.1~10.6 GHz）对混沌信号源的要求.

Abstract: In order to meet the requirements of chaotic signal sources for ultra-wideband chaotic communication systems, a new two-stage ultra-wideband chaotic circuit design is proposed to improve the bandwidth of chaotic signals effectively. Compared with the classic Colpitts chaotic circuit structure, the new structure uses an emitter follower with a collector inductor as the signal output end and introduced high-frequency resonance network. Thereafter, the signal power spectral density is compensated at high frequencies and the bandwidth was extended. The numerical solution of the new two-stage ultra-wideband chaotic circuit is obtained by MATLAB, and the bifurcation diagram and phase diagram of the new ultra-wideband chaotic circuit are obtained. The time domain diagram, spectrum diagram of the circuit output are also obtained through simulation analysis. It is shown that the new two-stage ultra-wideband chaotic circuit can generate 7.5 GHz wideband chaotic signal with a power within 20 dB, which meets the requirements of ultra-wideband signal indicators(3.1~10.6 GHz) for chaotic signal sources.
