Part FiveBeam Measurement and Calibration Solutions

YTBM0561 Beam measurement and calibration solutions have been designed to provide a low cost , portable and space-saving testing tool for 5G millime-ter-wave phased antenna array unit (AAU) and 5G millimeter-wave Front-end module (5G mmWave FEM) to verify and assure the produced beam perfor-mance well matching with the designed one. It also provides the special closed-loop path for beam calibration to optimize and compensate the non-ideal effects caused by the manufacturing process. Matlab and C++ envi-ronment makes it very flexible for user to design their-own algorithm for the optimizing beam by calibration. It is also very suitable for the mass production verification test of mmWave AAU or FEM.
