  1. Integrated Circuits (ICs) And Component EMC Testing
    9/28/2018

    High performance electronic devices demand the use of multi-chip package (MCP), system-on-a-chip (SoC) technologies, and more complex circuits. Due to the increase in emerging technologies, it has become impossible to ignore the large amounts of parasitic emissions generated by such complex integrated circuits (IC’s). Those who produce IC products for demanding electromagnetic environments must also take precautionary measures to test and pass all regulatory EMI and safety requirements to achieve early time to market and profitability. This white paper explores these standards and safety requirements and offers guidance for ensuring that IC products meet them.

  2. 5G New Radio Solutions: Revolutionary Applications Here Sooner Than You Think
    9/26/2018

    5G technologies promise to deliver higher data throughput, extremely low latency, and speeds up to 100 times faster than 4G. This paper explores the practical first steps of a roll out and focuses on the spectrum below 6 GHz as standards for millimeter-wave applications have yet to be determined.

    9/25/2018

    The FCC clamps down on local governments; spectrum auctions heat up in Germany and India; Intel, Huawei, and Samsung share hardware news; and Trump's tariff war casts a cloud over U.S. 5G rollouts, all in this edition of The Week in 5G!

  4. The Week In 5G: 9/18/2018 – Ericsson Says US Leads 5G Race, Verizon Rolls Out First 5G Home Internet, German Firms Want Speedier 5G Deployment
    9/18/2018

    Germany and France look toward 5G frequency licenses, India joins the U.S. and Australia in spurning Huawei, Verizon pushes for more U.S. firsts, and more, all in The Week In 5G. 

  5. How NB-IoT And LTE-M Fit Into The IoT Ecosystem: The Future Of Cellular IoT
    9/17/2018

    The future of the Internets of Things (IoT) will expand the use of cellular communications beyond smartphones and tablets to an extraordinary range of applications and connected devices. A significant number of these applications will require long-range connections. Two new standards, NB-IoT and LTE-M, have potential uses and some implementation options for device makers looking to add cellular connectivity.

  6. The Week In 5G: 9/11/2018 – AT&T Makes First Wireless Standards-Compliant 5G mmWave Connection, Verizon Claims First OtA Data Transmission On Commercial 5G NR Network
    9/11/2018

    This week sees another salvo of "5G firsts" and rollouts from competing wireless carriers in the United States.

  7. When Choosing Test Equipment, Don’t Forget the Interface
    9/5/2018

    When purchasing RF test equipment, it is tempting to concentrate on specifications, such as insertion loss, frequency range, or VSWR, without think ahead on the fact that a complex testing scheme usually involves integrating multiple pieces of equipment from multiple manufacturers. For multiple devices to work seamlessly together in an automated test flow, designers and engineers must also consider the interface that would be used to drive the testing equipment. This article discusses the differences in proprietary and generic interfaces, the benefits each type has to offer, and offers some solutions to potential interface barriers and how to remove them.

  8. EM Simulation Of 28 GHz Series-Fed Patch Antenna Array For 5G
    8/17/2018

    Series-fed patch elements forming an array are simulated to demonstrate antenna performance and beamforming including S-parameters, gain, and effective isotropic radiated power (EIRP) at 28 GHz. Beam steering is performed in one plane by adjusting the phasing at the input ports to each of eight elements.

  9. Beamforming For An 8x8 Planar Phased Patch Antenna Array For 5G At 28 GHz
    8/17/2018

    An 8x8 planar antenna array creates narrow beams capable of scanning large sectors in front of the antenna.  This example focuses on displaying typical simulation results for beams and possible plots of coverage from the full array and combinations of sub-arrays.

  10. Introduction To RF Matrix Switch Types And Functionality
    7/11/2018

    There are many types of RF matrix switches with configurations that distribute RF signals in very different fashions. This app note describes the functionality of these types of switches, their advantages and disadvantage, and how to choose the best switch for each application.
