  1. Generating Narrow Pulses With Highest Level Accuracy And Repeatability With The R&S SMA100B

    This app note discusses generating high-quality, narrow pulses using the R&S SMA100B analog RF and microwave signal generator. Thanks to a closed-loop level control concept also for narrow pulses, outstanding level accuracy and repeatability is available for pulse widths starting at 100 ns.

  2. Demystifying Polling Control In Zigbee Networks

    Understanding the polling features in the Zigbee standard can help to optimize the power consumption of IoT products. Take a closer look at Zigbee’s polling mechanism and an example using a fire alarm sensor application.

  3. Introduction To The FlexPort Mobile Backhaul Platform

    The evolution of networks to 4G has created new challenges for operators, such as the growth of base station capacities putting extra demands on backhaul networks. This paper introduces FlexPort Mobile Backhaul Platform solutions that look forward to 4G while supporting existing access technologies.

  4. Simulation Of MIMO Handset Antenna Array Performance With Varying Hand Positions

    Performance of a 12-port handset antenna array operating in LTE bands 42/43 (3400-3800 MHz) and band 46 (5150-5925 MHz) is analyzed in XFdtd for varying hand hold positions on the device.  The results computed include S-parameters, Gain, Efficiency and Envelope Correlation Coefficient.

  5. 5G Spectrum Recommendations

    New spectrum is critical for the successful launch of 5G mobile services, and many endeavors are ongoing to identify new suitable spectrum. Each available spectrum range has specific characteristics that make it suitable for certain deployment scenarios and applications. This paper discusses the dependencies between the 5G applications spectrum requirements and spectrum ranges that are attractive for 5G deployment services.

  6. An Introduction To Interference Hunting

    As radio systems have grown and become more complex, the number of interferers has also increased. This white paper introduces the basic concepts of interference hunting and explores the different types of interferers, how to analyze them, and the tools needed for the job.

  7. Evolution Of The Modern Receiver In A Crowded Spectrum Environment

    Unencumbered access to spectrum has been, and continues to be, critical to many government and commercial systems. As existing RF systems evolve and new communication systems are deployed, the need for additional spectrum bandwidth continues to grow. 

  8. How To Avoid Pitfalls When Designing And Manufacturing An RF Automated Test Equipment System

    Automated test equipment (ATE) system development and manufacturing is a difficult job for many design teams. However, most of the issues that cause stress and delays can be avoided if they are identified and addressed long before a program begins.

  9. Ten Cues You Need A 5G MIMO Channel Modeler

    How does Wireless InSite differ from planning tools? The most important differences emerge when users need to simulate 5G millimeter-wave and MIMO systems. This paper presents 10 cues that your organization may need a channel-modeling tool to supplement your 5G network planning efforts.

  10. Antenna Factor Concepts

    An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. This white paper explains the process of creating AF data and how to use it.
