  1. Use Case Possibilities With Bluetooth Low Energy In IoT Applications

    Within IoT systems, Bluetooth low energy technology can be connected to the internet to be used as “repeaters” to extend a system’s range. This white paper describes how Bluetooth low energy technology works and how it can be used to connect devices to internet-based services and applications.

  2. 5G Fixed Wireless Radio Validation Case Study

    Anritsu recently hosted a major network equipment manufacturer (NEM) at our factory in Morgan Hill, CA USA to perform some early validation of their 28 GHz 5G radios. The application is to use radios for 5G fixed wireless access to compete with fiber to the home. The NEM required the use of the Anritsu Spectrum Master™ MS2720T spectrum analyzer to test the performance of these next-generation 28 GHz 5G radios in a coverage mapping exercise. The spectrum analyzer was used to measure key parameters of the NEM prototype radio in a variety of real-world environments.

  3. Understanding Cable And Antenna Analysis

    A problematic base station can be replaced, but a cable and antenna system is not so easy to replace. This article covers fundamentals of cable and antenna analysis measurements: return loss, cable loss, and distance-to-fault (DTF).

  4. 802.11ad Testing With The Spectrum Master MS2760A Ultraportable Spectrum Analyzer

    802.11ad is a newer WLAN standard that offers throughput rates up to 7 Gbps. To achieve these speeds, the technology uses newly allocated mmWave ISM bands, specifically 57 to 71 GHz. 

  5. Making 5G NR A Reality

    To make 5G a reality, networks will require a unified and more capable air-interface design that will enable new levels of flexibility, scalability, and efficiency to meet expanding connectivity needs. This paper discusses the development and applications of 5G NR and how it relates to up and coming technologies.

  6. Using Surrogate Models For Antenna Placement On Large Platforms

    The Institute of High Performance Computing is continuously driven to develop cost-effective and innovative approaches to modeling, diagnosing, and solving electromagnetic compatibility (EMC) problems. 

  7. What is AESA RADAR Technology? — Advantages, Challenges, And Future Trends

    Active electronically scanned array (AESA) systems comprise an array of antennas forming a beam of radio waves that can be aimed in different directions without physically moving the antennas. What does the future hold for this technology?

  8. Design Guidelines For Schottky Rectifiers

    The known limitations of Schottky rectifiers can be measured and controlled, allowing for wide use in applications with switch mode power supplies. This application note differentiates the fiction from facts regarding this type of rectifier, and offers guidelines for designing a Schottky rectifier at optimal performance level and costs.

  9. Power MOSFET Basics: Understanding Gate Charge And Using It To Asses Switching Performance

    This app note defines the fundamental behavior of MOSFETs and analyzes the switching behavior of a MOSFET when used in a practical application circuit, how to choose the right device from minimal information on a datasheet, and methods for assessing the MOSFET performance.

  10. Power Inductors 101
