  1. RF Filtering For 5G Millimeter Wave Applications

    This white paper presents and discusses some of the areas of 5G communications that will be implemented in the millimeter wave (mmWave) region of the RF spectrum. The paper will also offer a guide for available RF filtering options at these frequencies, review mmWave frequencies and their applications, and cover what filtering technologies will be available for use at mmWave frequencies.

  2. How One Military Plane Fights California Wildfires

    The California Air National Guard used the MQ-9 Reaper unmanned aerial vehicle (UAV) to help fight the Carr and Mendocino wildfires by capturing bird’s eye images and videos of the damage. 

  3. Understanding Miniaturized Automotive Coax Terminals

    Connectivity has become increasingly more important as the global automotive industry progresses towards safer, greener, and more comfortable driving. Automotive interconnections and the increase volume of transmitted data now require the use of high RF/high-bandwidth connections. TE Connectivity offers the MATE-AX miniaturized coaxial terminal solution to provide the industry 9 GHz of immediate RF performance and capability up to 20 GHz in much smaller, lighter, more affordable layouts.

  4. Role Call: Senior Software Engineer

    Role Call, a series on RF Globalnet, takes a “peek behind the curtain” to help answer the questions related to different jobs and career paths in the RF and microwave industry. Recently, Pat Lyons, Senior Software Engineer/LabVIEW Developer at In-Phase Technologies, Inc., took time to answer some questions about his occupation.

  5. Lessons For Our Fight Against Subtle Sexism

    If we're to address subtle sexism, we don’t just need a plan for how to react; we need a plan to draw a line in the sand, so we know when it’s been crossed. Even harassers likely have challenges understanding where the line is after they’ve seen it crossed for so long without regard.

  6. Today’s RF Semiconductor Landscape is Changing – Why?

    What are the driving forces behind today’s rapidly changing RF semiconductor landscape? This article delves into the two major driving factors of change in the industry: the desire for ubiquitous sensing and the demand for more and better connectivity.

  7. Q&A With David Lu, VP, D2 Platform & Systems Development, AT&T

    In June, David Lu discussed his company’s perspectives on 5G services — as well as his own — at IMS 2018’s 5G Summit in Philadelphia. Here, he delves a little bit deeper into 5G’s development and future, and discusses his own career.

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

    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

    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. Understanding Model 855 Phase Coherence

    This application note describes the achievable channel-to-channel phase coherence of Berkeley Nucleonics Model 855 multi-channel signal sources.
