This article covers the following comparison of measurements vs. analysis for receiver dynamic range metrics in a phased array hybrid beamforming architecture. A commercially available 32-channel development platform is used to validate the analysis with measurements. The receiver analysis for subarray beamforming is reviewed, with an emphasis on handling the differences between signal gain and noise gain at the point where signals are combined in the analog subarray. An analysis is shown for the development platform receiver performance and compared against measured results. A summary of the results is discussed with the intention to provide a measured vs. modeled reference point that can be leveraged to predict the performance of larger systems.
