  1. Ten Cues You Need A 5G MIMO Channel Modeler

    How does Wireless InSite differ from planning tools?  The most important differences emerge when users need to simulate 5G mmWave and MIMO systems.  This paper presents ten cues that your organization may need a channel modeling tool like Wireless InSite to supplement your 5G network planning efforts.

  2. Antenna Factor Concepts

    An antenna factor (AF) is the comparison between the field level presented to the antenna and the actual voltage produced by the antenna at its connector. The AF varies with frequency at the same presented field strength, but at a different frequency, the produced voltage at the connector is not constant. This white paper explains the process of creating AF data and how to use it.

  3. 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.

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

    The US Marines' “mega-drone" is intended carry the same payload as an F-35B and fly a radius of up to 700 nautical miles at 30,000 feet. This Marine Air Ground Task Force Unmanned Aircraft System-Expeditionary (or MUX, for short) also will be able to fill “an extremely broad range of missions."

  5. Time Domain Analysis Using A Network Analyzer

    This white paper focuses on the time domain analysis displays generated from vector network analyzers (VNAs). The paper will also cover frequency domain basics, an in-depth overview of how a time domain display is created from frequency domain data (S-parameters), and steps for applying the time domain display to common problems in RF systems.

  6. 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.

  7. 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. 

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

    The antennas to be used for 5G applications are essential for beamforming operations that play an important part in next generation networks. This white paper provides an overview of the fundamentals of beamforming technology, including signals, antennas, and current transceiver architectures. The paper also discusses calculation methods for radiation patterns and a number of simulations results, as well as some real world measurement results for small linear arrays are shown.

  9. 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.

  10. 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.
