    4/23/2019

    Plus, Huawei shrugs off U.S. aggression en route to a banner Q1, the U.S. preps for its largest spectrum auction ever, Verizon launches a 5G technology contest, and more, all in this edition of The Week in 5G.

  2. Design And Simulation Of 28 GHz Beamforming System And Antenna Array For 5G Network Base Stations
    4/18/2019

    This example describes a more developed 28 GHz antenna array capable of forming multiple beams for use in applications such as 5G network base stations. The system consists of three parts: a Rotman lens beamformer with seven input ports and eight output ports, a series of stripline Wilkinson power dividers to split each Rotman output into eight equal signals, and an 8x8 patch antenna array. The design process consists of three separate stages. This example will describe the creation of each stage of the device and evaluate the performance of the individual stages and the full device.

  3. Connectivity For Next-Generation Mobility
    4/16/2019

    Powertrain electrification and automation are the key technology drivers that will ultimately lead to a new generation of all-electric, fully autonomous vehicles. At the same time, with the emergence of new business models, utilizing cloud and big data technologies, there will be a shift away from car ownership towards mobility services provided by new types of vehicle fleet operating companies. This white paper describes TE Connectivity’s vision for the next generation of mobility and its impact on vehicle architectures. It also shares how TE’s technology and portfolio address critical connectivity challenges the industry is experiencing.

  4. Choosing RF Switches For High-Power Applications
