Abstract

The possibility of generating ultrabroadband chaotic oscillations within a frequency range up to 60 GHz with a bipolar SiGe heterojunction transistor is demonstrated. The uppermost frequency of this range is determined by the cutoff frequency of the active generator element. Such a possibility appears after the generator structure is complemented with an additional nonlinear circuit, in which chaotic oscillations can be developed up to the aforementioned frequency. Some results of the experimental study of one generator configuration based on lumped elements are presented.

具有附加非线性电路的混沌微波振荡的超宽带发生器

摘要

演示了使用双极SiGe异质结晶体管在高达60 GHz的频率范围内产生超宽带混沌振荡的可能性。该范围的最高频率由有源发电机元件的截止频率确定。在发电机结构补充了一个附加的非线性电路之后，这种可能性就出现了，在该电路中可以将混沌振荡发展到上述频率。提出了一种基于集总元素的发电机配置实验研究的一些结果。
