Rohde & Schwarz App Note: Generating Multiple Phase Coherent Signals

Rohde & Schwarz App Note: Generating Multiple Phase Coherent Signals - RF CafeTesting multi-antenna systems such as phased array or beamforming antennas requires a test system capable of providing multiple signals with constant phase relationships between them. The coherent test signals must have a specific or definable phase difference (relative phase) and definable amplitude. Some of the challenges for such a test system include compactness, phase control capability and simplicity in handling. In particular, phase stability between the channels is of importance.

This application note explains how to generate phase coherent signals. It details what to consider and how to configure the test setup and describes in detail how to best calibrate the relative phases and timing between the individual channels and when to repeat the calibration.

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
