  1. How To Verify Beamformer ICs For Phased Array Antennas
    4/10/2019

    Beamforming using phased array antennas is a common technology for radar and electronic warfare in the aerospace and defense industry. In satellite communications and 5G NR, phased array beamforming is becoming a default concept. Integrated RF beamforming ICs include phase and gain adjustment per path as well as amplification capabilities for the TX and RX channels. Such beamformer ICs support four or more antenna elements from one input signal. Full characterization and calibration requires simultaneous assessment of all ports. This article discusses the process of verification for these beamformer ICs for phased array antennas.
