    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.

  2. Q&A With David Lu, VP, D2 Platform & Systems Development, AT&T
    8/20/2018

    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.

  3. 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.

  8. Comparison Of Jitter Measurements In The Time And Frequency Domain
    8/14/2018

    When analyzing the robustness of data transmission systems, jitter is a key indicator. It is recommended to use jitter measurement instruments for both the time and frequency domain in order to differentiate between fast and slow moving artifacts. This white paper compares measurement results of jitter in the time and frequency domain.

  9. Understanding Diamond As A Material For RF Packaging
    8/13/2018

    Diamond’s unique mechanical, optical, thermal, and electrochemical properties make it effective for a range of industrial uses. Synthetic  and natural diamonds display the same chemical structure and physical properties, but synthetic diamonds offer control over defects and synthesis conditions, allowing manufacturers to optimize and tailor their properties.
