As the title suggests, I am inviting the reader to take a brief walk with me and discuss the interesting subject of microwave noise. My goal is to provide some highlights on this subject, from its basic pillars based on physics to the latest engineering publications. A solid understanding of noise cannot but stand on the shoulders of the physicists who have continually been looking at overcoming the limitations of any theoretical model to explain nature. Names like Brown, Einstein, and Nyquist must be mentioned before focusing on the applications of those ideas, which started more than 100 years ago: How do you describe noise when considering microwave circuits? How do you characterize noisy microwave circuits nowadays?

噪声简介：从基本概念到高级测量技术


正如标题所示，我邀请读者与我一起散步并讨论微波噪声这个有趣的话题。我的目标是提供有关该主题的一些亮点，从基于物理学的基本支柱到最新的工程出版物。对噪声的扎实理解只能站在物理学家的肩膀上，他们不断寻求克服任何理论模型的局限性来解释自然。在关注这些想法的应用之前，必须提及布朗、爱因斯坦和奈奎斯特等名字，这些想法始于 100 多年前：在考虑微波电路时，如何描述噪声？您如何描述当今嘈杂的微波电路的特征？
