  • How To Verify Beamformer ICs For Phased Array Antennas

    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.

  • Aperture Tuning: An Essential Technology In 5G Smartphones

    Antenna aperture tuning is essential to enable smartphones to operate efficiently over the ever-increasing range of RF frequency bands and support the transition to 5G. Smartphones need more antennas to support growing RF requirements such as new 5G bands, MIMO, and carrier aggregation (CA), but there is less space for these antennas due to changes in smartphone industrial design. As a result, antennas are becoming smaller, potentially reducing antenna efficiency and bandwidth. Aperture tuning compensates for this problem by allowing antennas to be tuned to operate efficiently on multiple bands and increasing Tx and Rx performance by 3 dB or more.

  • The Importance Of Antenna Beamwidth In RF Testing
    The Importance Of Antenna Beamwidth In RF Testing

    Antenna beamwidth determines the expected signal strength given the direction and radiation distance of an antenna. The beamwidth will vary given several different factors such as the antenna type, design, orientation and radio frequency. This white paper presents a better understanding of beamwidth and how it influences a test environment is critical to accurate and repeatable tests.

  • Distributed Antenna System (DAS) For IoT, Cellular And Other Wireless Applications

    Distributed Antenna Systems (DAS) are used to provide strong and reliable wireless connectivity in location where connectivity is a problem with standard wireless routers or cellular connectivity. This app note discusses the use of DAS for IoT, cellular and other wireless applications.
