  1. 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 millimeter-wave (mmWave) ISM bands, specifically 57 to 71 GHz. With applications including docking stations, virtual reality, media downloads, and wireless HD video, 802.11ad (or WiGig) is becoming a standard technology for most major hardware manufacturers. As these technologies become established and grow in the marketplace, the need for affordable, reliable test will be ever-present. At mmWave frequencies, however, test equipment has historically been extremely expensive and difficult to characterize. As a longtime leader in mmWave technology, Anritsu has leveraged decades worth of experience and knowledge to bring forward new equipment to help companies overcome these challenges. In particular, the Spectrum Master MS2760A Ultraportable Spectrum Analyzer — an innovative new mmWave spectrum analyzer — is available today for use in 802.11ad testing.

  2. 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 white paper discusses the development and applications of 5G NR and how it relates to up and coming technologies like Gigabit LTE, smart technologies, and the Internet of Things.

  3. 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. 

  4. 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?

  5. 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.

  6. 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.

  7. Power Inductors 101

    Power inductors typically are used for energy storage in DC/DC converters or high-noise filter applications, including motor speed control, adjustable lighting, DC power conditioning, and more. This article delivers the basic information for understanding power inductors, their uses, and benefits.

  8. The Easy Way To A 1 Gbps RF Front-End On Smartphones

    This Qorvo article highlights the need for higher order modulation, carrier aggregation, and 4x4 MIMO technologies in the journey to faster download speeds, and how to add 1 Gbps front-end modules to smartphones.

  9. Remotely Monitoring Mission Critical Positive Train Control Networks

    Positive Train Control (PTC) is an advanced communications system to minimize train accidents by automatically controlling train activity. This includes real-time monitoring of static and dynamic conditions that require the train to slow or stop. The On Board Computer (OBC) monitors these conditions, and in the event of an improper response from the engineer, the OBC takes control and slows or stops the train within a safe braking distance from the restriction. Anritsu was selected to meet the interference study technical challenge. Anritsu’s MS27101A, 9 kHz - 6 GHz, 1⁄2 rack mount Remote Spectrum Monitor™ web-based automated data capturing hardware and Vision™ database software platform were selected as the unique, single supplier solution capable of meeting the interference study technical challenges.

  10. 5 Common Causes Of Frequency Drift In Crystal Oscillators And Their Solution

    Setting the initial frequency of an oscillator to the most precise values can be frustrating when you realize that the oscillator will not be able to maintain that frequency. This article covers multiple sources of frequency instability, and presents the Ultra-Stable OCXO as a fix-all solution.
