This focused issue is sponsored by the IEEE Microwave Theory and Techniques Society (MTT-S) MTT-11 Technical Committee (TC) on Low-Noise Techniques. Each TC in the MTT-S is made up of international researchers with a variety of backgrounds and research interests. The low-noise TC changes on a regular basis and brings in researchers with new interests. Low-noise techniques cover everything from fundamental noise sources down to the quantum level and up to complete systems. Of course, nonlinear processes, semiconductor devices, and oscillator noise sources are also covered, as you will see in the articles in this issue. The goal of an MTT-S TC is to promote workshops and educational publications and to maintain an everimproving knowledge base for the Society in a specific area.

本期焦点问题由 IEEE 微波理论与技术协会 (MTT-S) MTT-11 低噪声技术技术委员会 (TC) 赞助。 MTT-S 中的每个 TC 均由具有不同背景和研究兴趣的国际研究人员组成。低噪音 TC 会定期变化，并带来新的兴趣研究人员。低噪声技术涵盖了从基本噪声源到量子级别直至完整系统的一切。当然，非线性过程、半导体器件和振荡器噪声源也包括在内，您将在本期的文章中看到。 MTT-S TC 的目标是推广研讨会和教育出版物，并维持协会在特定领域不断完善的知识库。
