  1. Shielding Effectiveness Test Guide

    Many products incorporate electronics and wireless communications and need RF interference testing. This requires shielding enclosures that need proper testing to ensure their correct operation.

  2. Marines' “Mega Drone” Illustrates Need For High-Efficiency Microwave Power Modules

    A recent Military article revealed details about the US Marines' “mega-drone,” an impressive Group 5 aircraft (the largest class of military UAV) that can carry the same payload as an F-35B and fly a radius of up to 700 nautical miles at 30,000 feet, and will be able to fill “an extremely broad range of missions.

  3. Time Domain Analysis Using A Network Analyzer

    This white paper focuses on the time domain analysis displays generated from vector network analyzers (VNAs), as well as frequency domain basics, an in-depth overview of how a time domain display is created from frequency domain data (S-parameters), and more.

  4. 3 Common Pitfalls Of 802.11ax DVT (That Test Developers Should Avoid)

    The transition from previous 802.11 standards, such as 802.11n and 802.11ac, to 802.11ax adds several new technologies and performance requirements that need to be fully tested. However, there are a number of challenges in designing these test scenarios.

  5. Overcoming The RF Challenges Of Full-Screen Smartphones

    The future generations of smartphones aim to design and build next-generation handsets that deliver a compelling user experience. These next-generation devices must be able to have both an attractive form factor and the ability to deliver high performance connectivity. 

  6. Millimeter-Wave Beamforming: Antenna Array Design Choices And Characterization

    This paper dicusses fundamentals of beamforming technology, including signals, antennas, and current transceiver architectures. The paper included calculation methods for radiation patterns and some simulations results, as well as showing some real-world measurement results for small linear arrays.

  7. Fundamentals Of An RF Design

    This white paper covers the fundamentals of designing an RF communication system, including coverage on the transmission medium, wave propagation, free space path loss, transmit and receive portion, link design and other key components. The article will also discuss the required test equipment and considerations during the design, development and verification processes.

  8. Harmonic Injection Doubles Ultra-Wideband TWT RF Output

    Using harmonic injection on an ultra-wideband TWT is a relatively new concept that works to cancel the naturally-generated second (and/or third) harmonic within the TWT, and therefore recover the available beam power back into the low-end fundamental frequencies. 

  9. The Road To 5G

    Meting 5G requirements may seem daunting, but simulation already can be used to develop understanding and explore innovative solutions. FEKO offers comprehensive solutions for device and base station antenna design, while WinProp will determine the requirements for successful network deployment.

  10. Using Microwave And Millimeter Wave Radiometers

    Microwave radiometric sensors are devices used to detect electromagnetic energy. This white paper expresses the reasoning for certain radiometer calibrations and other modes of operation in regards to the sensor’s subsystems.
