    5/31/2019

    This article examines the use of broadband bypass capacitors for use in microwave and mmWave frequencies, especially those used in RF applications and optical communications.

  2. The Price Of Reliability: Considerations For Buyers
    5/31/2019

    By making a small component change, one could extend an implantable medical device's reliability and lifespan by preventing battery related complications. This paper explores the cost of device failures and discusses how proper testing and supplier considerations can help capacitor sourcing.

  3. The Future Of IoT Will Require LTE Connectivity
    5/22/2019

    As the promise of a wirelessly connected world becomes a reality, there is a growing need for LTE technologies that address low cost, long battery life, security, and reduced complexity — all critical components for IoT.

  4. The Increasing Importance Of Increasing Ports: Addressing The Challenges Of Multiport Test
    5/21/2019

    A multiport VNA significantly reduces test time to deliver highly accurate measurements on multiport devices. The flexible modular configuration, fast measurement times, and high performance make VNAs the right tool for multiport testing. 

  5. The Essential Signal Generator Guide: Building a Solid Foundation in RF – Part 2
    5/21/2019

    In order to offer customers a robust and reliable high-speed wireless connection, you first need the right signal generator. This white paper is the second part of a guide to understanding signal generators. It offers an overview of various modulation schemes, the importance of spectral purity, and the benefits of distortion.

  6. Cost Effective Full-Duplex Systems Utilizing a Semi-Custom Approach
    5/15/2019

    The requirements of modern datalinks in the UAV and large airframe market present challenges for systems designers. Many modern communication systems often require full-duplex operation, and several systems may be operating on a single airframe.

  7. Extending The Range Of A Low Power UAV Radio
    5/15/2019

    Low-power UAV radio systems, though designed for short distance communications, can be an inexpensive and reliable means of communications over greater distances – especially when the application is small UAS platforms.

  8. IoT Standards: The End Game
    5/15/2019

    It can be confusing to try to pick standards while waiting for 5G or NB-IoT deployments. This article answers the question of which standards are best to use and looks ahead at the future of wireless technologies to help gain a better perspective as to where things are headed.

  9. Measurement Of Beamforming Antenna In Transmit Mode
    5/14/2019

    Rapid and accurate verification of beamforming weights is required for example, for codebook generation, or beamforming algorithm development or verification. This white paper describes the unique application of Rohde & Schwarz’s vector network analyzers to fully characterize the passive part of multi-element antennas intended for beamforming.

  10. How Big Is A Wavelength?
    5/13/2019

    In traditional arrays an inter element spacing of less than half the wavelength (<λ><λ/2) is required to mitigate grating lobes. To understand the shift in system design this brings about, this paper looks at the physical scale of different wavelengths compared to some familiar references.
