    1/24/2019

    Robotics and unmanned applications rely on connectivity solutions that combine miniaturization with ruggedness for high performance. Fischer Connectors translates these requirements into innovative custom solutions with the Fischer MiniMax Series connectors.

  2. Countering Small Unmanned Aircraft Systems (sUAS)
    1/10/2019

    The small Unmanned Aircraft Systems (sUAS) market has experienced exponential growth with the advent of brushless electric motors and high energy density lithium batteries. However, this accessibility also increases potential for weapon platforms, privacy violations, and interference.

  3. Optimizing RF And Microwave Spectrum Analyzer Dynamic Range
    1/2/2019

    Dynamic range specification determines whether or not low-level signals will be visible in the presence of large signals and therefore is one of the most important performance figures for a spectrum analyzer. 

  4. Building A Fixture For C-Band Satellite Communications Power Amplifier Applications Using Two GaN HEMTs
    12/19/2018

    Wolfspeed, a Cree Company, developed an application circuit that demonstrates the ability for their CGHV1F025S to operate between 4400 MHz to 5000 MHz for satellite communication applications. The circuit utilizes two devices connected using a Wilkinson combiner in a balanced configuration. This application note describes the typical performance that has been achieved and what can be expected when evaluating the application fixture.

    12/17/2018

    Selecting the right testing instrument for a project is essential to get products to market faster. This is Part 1 of a two-part white paper discussing signal generators. This paper offers an overview of the fundamentals of signal generators, enabling users to make the right decision when selecting one for different applications.

  6. What’s Best? Wi-Fi 6 (802.11ax) Or 5G?
    12/17/2018

    Every time a new cellular phone standard comes out, we see new claims about the “end of Wi-Fi.” The 5G message is that it will cover homes and buildings both inside and outside. This begs the question: What will be the impact of the next generation of Wi‑Fi, Wi-Fi 6 (802.11ax)? 

  7. White Paper: Modeling RF Propagation In Mines Using Wireless InSite
    12/12/2018

    This paper presents results from modeling RF propagation in a mine using Wireless InSite®. The Edgar Mine in Idaho Springs, CO provided the realistic scenario for the model. The path loss exponent was evaluated for a 5m section of the modeled mine by considering three different materials and three different standard deviation of surface roughness values for dry granite. When comparing this simulated data with data retrieved from the Edgar Mine it was determined that the Uniform Theory of Diffraction (UTD) ray tracing code, of Wireless InSite, can portray a communications system within a mine environment.

  8. White Paper: Complex 3D Modeling Of Sea To Land Scenario
    12/12/2018

    This paper presents results from sea to land propagation using Wireless InSite®. The effort explores the effects of various elements in the scene and how they impact the results. The various elements in the scene include the ships out at sea, the ships docked, the docks themselves, the buildings around the dock area, and the material properties of each.

  9. Advancements In Broadband Amplifiers
    12/12/2018

    The basic amplifier design and mode of operation have remained relatively unchanged until recently. This white paper discusses recent advancements in amplifier design that provide flexibility and efficiency, creating a new class of “smart amplifiers.” 

  10. Automotive Radar Technology, Market And Test Requirements
    12/5/2018

    The automotive industry is continuously adding more radar sensors that support drivers in critical situations. Radar enables quick, precise measurement of the radial velocity, range, azimuth angle and elevation angle of multiple objects, so it is often used in advanced driver assistance systems (ADAS).
