  3. Best Practices to Accelerate 5G Base Station Deployment: Your RF Front-End Massive MIMO Primer
    11/8/2019

    Strategy Analytics predicts an explosive growth of emerging 5G networks. They forecasted the number of new base station sectors deployed to double between 2018 and 2024. This rapid 5G growth will result in equipment for nearly 9.4 million new and upgraded wireless base stations deployed by 2024. Many of these 5G base stations will incorporate massive MIMO antennas. These new 5G network architectures incorporating massive MIMO antennas are pushing always-on connectivity to the outer edges of the cellular network. This article covers everything to know about the fundamentals of the RF front-end in the massive MIMO base station.

  4. What The Heck Is An OCXO Oscillator?
    11/8/2019

    OCXO stands for Oven Controlled Crystal (Xtal) Oscillator. OCXOs are the top performing type of quartz crystal oscillators at the expense of power. Other types of quartz crystal oscillators include TCXO, VCXO, and just plain XOs. 

  5. Multi-Stage GaN Power Amplifier Reference Design
    11/7/2019

    This app note demonstrates Wolfspeed’s GaN HEMT technology capabilities with respect to harmonic content, PAE, and SWaP. It also describes the typical performance that has been achieved and that which can be expected when evaluating the demonstrator.

  6. Design And Modeling Of A Solid-State Transmit/Receive Module For Radar Applications
    11/5/2019

    Active phased-array radars (APARs) typically require solid-state T/R modules with high-output power, low-noise figure, third-order intercept, and sufficient gain in both transmit and receive. A T/R module is 40-60% of the overall RF front-end cost, so it is important to use an architecture that meets all requirements with the most cost-effective technology. This white paper overviews various solid-state semiconductor technologies for T/R module development and describes a design methodology that includes the modeling/analysis of a T/R module.

  7. Definitive Guide to UAVs
    10/31/2019

    In the defense sector, unmanned systems have continued to transform military reconnaissance and surveillance missions. In fact, unmanned platforms and capabilities have become so broad that they’ve branched into more than a dozen categories and acronyms. This article provides an overview of the different acronyms associated with unmanned systems.

  8. Understanding RF Signal-Combining Technologies
    10/30/2019

    This article explores options for combining or separating signals and is intended to help engineers determine which component -- or combination of components -- is most advantageous, given the application.

  9. Phase Stability, Loss Stability, And Shielding Effectiveness
    10/29/2019

    This white paper addresses phase stability, loss stability, and shielding effectiveness in cable assemblies exceeding 20 feet. Stability and shielding effectiveness behavior of long length assemblies are not well documented due to the small number of requests for such assembly types and the lack of standardized test procedures. This document also offers basic performance information pertaining to one specific type of GORE® microwave RF assembly which would typically be used in a test environment where occasional coiling/uncoiling and random movement would occur.

  10. Improving T/R Module Test Accuracy And Throughput
    10/24/2019

    This white paper provides an overview of the basic building blocks of a phased array system and discusses how the nature of their design leads to a challenging test environment. It also shows how the R&S®ZVAX-TRM expands the capabilities of the R&S®ZVA to perform a wide range of T/R module measurements with just a single connection. Real measurement configuration examples are shown to highlight the flexibility required for T/R module testing.
