Measuring Phase Noise with Baluns

Differential clock and timing devices are commonly characterized for phase noise using baluns. While deceptively simple to use, baluns perform a fairly complicated process that can unknowingly introduce artifacts into measured results. This article describes such artifacts, discusses why they appear and how to eliminate them. Recommendations are provided for selecting a balun and using it to accurately characterize devices for phase noise.
