  1. MMICs vs. Discrete Circuits, What Are The Trade-Offs?
    10/15/2019

    One major decision a PA module designer must make during development is the choice of architecture utilized in the amplification circuit. The two most widely used options are a Monolithic Microwaves Integrated Circuit (MMIC), or a design built around discrete components. Each approach provides advantages and particular challenges.

  2. High Power Switched Filter Bank Options For RF Communications And Electronic Warfare (EW) Applications
    10/15/2019

    Switched filter banks are beneficial to Radio Frequency (RF) communication systems and are utilized in both receivers and transmitters to reduce signal interference from harmonics, spurious emissions, strong signal interferers, and to limit noise power for optimized system performance.

  3. What Can mmWave Do For 5G Backhaul?
    10/9/2019

    The backhaul segment of the network is traditionally made up of the intermediate point-to-point links between the core (or backbone) network and the small subnetworks at the network edge, where the base stations are. Since 5G is aiming for multi-Gbps data rates for subscribers, all this data will need to be backhauled at much higher rates, too.

  4. Development Of The Next-Generation Openvpx-Based Embedded System Standard
    10/8/2019

    Something exciting is happening in the service representative community. Representatives from three different programs, one from each of the U.S. Department of Defense (DoD) services, have come together with a common objective to solve their respective acquisition problems with an agreed upon, open architecture standard. Here is the final part of a 3-part article covering the SOSA (Sensor Open System Architecture) Consortium’s efforts.

  5. Introduction to ANSYS® 5G Antenna Solutions
    10/3/2019

    5G promises a spectacular world of wireless communications systems. It presents lucrative opportunities in consumer electronics, internet-of-things (IoT), advanced driver assistance systems (ADAS), telecommunications, entertainment, medical, transportation and other sectors. This white paper addresses the complexity of designing various points in these kinds of systems, and discusses how ANSYS products are a possible solution to design and simulate antenna systems, antenna-to-antenna coupling, environmental effects on signal propagation as well as V2V and V2X communication for traditional and autonomous vehicles.

  6. Wideband Integrated Upconverters And Downconverters Boost Microwave Radio Performance While Reducing Size
    10/3/2019

    Analog Devices recently launched a pair of highly integrated microwave upconverter and downconverter chips operating over a wide frequency range with 50 Ω match from 24 GHz up to 44 GHz. Performance attributes of the ADMV1013 and ADMV1014 ease the design and implementation of small 5G millimeter wave (mmW) platforms that cover the popular 28 GHz and 39 GHz bands in backhaul and fronthaul, as well as many other ultrawide bandwidth transmitter and receiver applications.

  7. Introduction Into Theory Of Direction Finding
    10/2/2019

    While direction finding for navigation purposes is becoming less important, there is a growing demand for determining the location of emitters as the mobility of communications equipment increases. The importance of direction finding lies in the fact that spread-spectrum techniques are increasingly used for wireless communications. This means that the spectral components can only be allocated to a specific emitter if the direction is known. Direction finding is therefore an indispensable first step in radio-detection, particularly since reading the contents of such emissions is usually impossible.

  8. Functionality Testing Of Automotive Infotainment Devices
    9/27/2019

    Modern day vehicle interactivity takes place on the centrally placed touchscreen head unit display (HUD) on the car dashboard and their infotainment systems have become a central hub for a wide range of vehicular functionality. These systems provide driver entertainment and information by integrating different functions. Examples include in-vehicle connectivity with wireless devices and connecting with external communications, transmission, radio and satellite network providers. This article discusses the challenges of functionality testing in automotive infotainment devices and presents a test and measurement solution.

  9. The Wi-Fi Evolution
    9/26/2019

    Since Wi-Fi was first released to consumers in 1997, its standards have been continually evolving – typically resulting in faster speeds and network/spectrum efficiency – and it can be difficult to keep track of new standards. This paper is meant to help you understand the basics of Wi-Fi standards, and provides and overview of the evolution of Wi-Fi technologies.

  10. Resolving Interference In A Crowded Wi-Fi Environment Using BAW Filters (Part 2)
    9/26/2019

    There are any number of strategies that consumers can try to fix interference problems with Wi-Fi in their homes, but as an RF engineer, how can you design a Wi-Fi access point that addresses the biggest interference issues from the outset?
