数字低噪声梳状谱发生器研究

Development of the comb spectrum generator of low additional phase noise and high efficiency

分析了经典梳状谱发生器的原理及应用局限,提出了用数字电路设计的梳状谱发生器——自相关梳状谱发生器.该方案已应用在小型Rb原子振荡器中,满足了Rb原子振荡器对倍频低附加相噪和高倍频效率的要求.

This paper analyses the mechanism and limitation of several classical comb spectrum generators firstly, and then presents a novel scheme of the comb spectrum generator, so called the self-correlation comb spectrum generator. The latter meets the requirements of low additional phase noise, high efficiency and good power stability and has been applied a miniature rubidium atomic oscillator of our laboratory.
