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.
