Establishing Phase Reference Standards for RF Cable Assemblies: Design, Test, and Production Control (Download)
High-frequency systems such as phased-array radar, satellite communications ground stations, antenna arrays, and multi-port test platforms rely on tight inter-channel phase alignment to function correctly. In these applications, even small phase deviations between signal paths can degrade beam pointing accuracy, reduce gain, or compromise measurement integrity.
Thus, RF cable assemblies require not only compliance with insertion loss or impedance specifications, but also a clearly defined and repeatable phase reference.
