Calibration-free beamforming of 28 GHz mmWave Antenna Board

This video shows introduction and demonstration of Calibration-free beamforming of 28 GHz mmWave Antenna Board with FutureAccessTM Type-C from Fujikura using R&S®ZNA from Rohde & Schwarz. Highlight contents ・Introduction of 28 GHz mmWave Antenna Board and Fan out Wafer Level Package based Beamformer IC and Frequency Converter IC with low cost design ・Introduction of measurement set up in anechoic chamber using direct far field (d = 6 m) and rotating tables ・Introduction of R&S®ZNA using phase coherent mode and time sweep mode ・Explanation of absolutely accurate phase control using original transmission-line based phase shifter in the Beamformer IC ・Demonstration of phase calibration, phase distribution of phased array antenna and calibration time ・Comparison of beam patterns between without calibration and with calibration ・3D beam pattern shape to understand precise beam control These results show effective demonstration of calibration-free beamforming with precise beam control, which benefits customers with optimal TCO and reduced development time.
