摘要

在本文中，我们提出了一种基于混沌Colpitts振荡器的自主微波混沌发生器，其频谱功率密度在0.5- 15ghz范围内平滑分布。混沌发生器采用BFP620晶体管作为非线性元件。给出了利用先进设计系统(ADS)软件进行仿真的结果。实验结果证明了该电路在-40dBm左右产生均匀频谱的高斯白噪声(WGN)的可能性。这一特性使得该电路在多波段超宽带通信系统、无线电认知应用和无线电工程测量中具有广阔的应用前景。

New Microwave Chaotic Generator with Flat Spectrum Envelope in the Range of 0.5–15GHz

In this paper, we present a novel autonomous microwave chaotic generator based on chaotic Colpitts oscillator with a smooth distribution of spectral power density in the range of 0.5-15 GHz. The chaotic generator is based on the BFP620 transistor as nonlinear component. Simulation results using ADS (Advanced Design Systems) software tool are presented. The obtained results justify the possibility of generation White Gaussian Noise (WGN) signal from the proposed circuit with a uniform spectrum around -40dBm. This property makes the circuit promising for multiband UWB communication systems, radio-cognitive application and radio engineering measurements.
