Low-Noise Techniques [From the Guest Editors' Desk]

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.
