  1. Why USB Vector Network Analyzers (VNAs)?
    5/12/2017

    USB Vector Net Analyzers (VNAs) offer benefits such as separating the measurement module from the processing module, measurement results brought to any external PC using VNA software, and the latest OS processing power, bigger displays, and simplified maintenance of the analyzer.

  2. Mitigating Phase Noise From Vibration In Air Traffic Control And EW Radar Systems
    5/5/2017

    Internal phase noise effects generally take the form of impurities or non-idealities in oscillator circuits and resonators. External effects can be caused by vibration by certain components and circuits. 

  3. 5G In Perspective: A Pragmatic Guide To What's Next
    5/5/2017

    The world’s communications and other connected technologies are evolving rapidly toward 5G in the hope of bringing about new and exciting solutions for deep learning, artificial intelligence, and “ambient awareness.” 

  4. Top 4 Sources Of Microvibration On Spacecrafts
    5/5/2017

    It is vital to understand how to design a spacecraft with precise functionality for the journey to earth’s orbit and beyond. Eliminating as many vibrations as possible is crucial so that they do not interfere with functionality during pre-launch transportation and powered flight. One type of vibration is microvibrations. This article presents the top four sources for vibration and microvibration on spacecrafts and how to spot them.

  5. Noise Figure: What Is It And Why Does It Matter?
    5/1/2017

    Noise figure is a key parameter that quantifies receiver performance by measuring how low a power a signal receiver can detect. This white paper covers the basic principles of noise figure, how to make sense of its specifications, how it is measured, and why this parameter is important in high-performance applications.

  6. What’s Better – TWTAs Or SSPAs?
    5/1/2017

    Depending on the specific application and end-customer requirements, different parameters may be critical to the amplifier design. The ultimate goal is to create an amplifier that is specification compliant, reliable, low-cost, and easy to maintain.

  7. Hyundai MOBIS Automotive Group Uses FEKO For Shielding Effectiveness Simulation
    4/26/2017

    Hyundai MOBIS planned to improve the effectiveness of shielding enclosures that protect against illumination from both external fields and EM leakage from electronic products in the presence of apertures and slots used to accommodate visibility, ventilation, and access to interior components.

  8. Using Altair FEKO To Facilitate Development Of The World's Smallest TV Antenna
    4/26/2017

    At the Universidad Autónoma del Estado de Morelos (UAEM), students and researchers have developed an antenna miniaturized into a smaller footprint, while improving signal stability. This case study discusses the university's use of FEKO to facilitate development of the world’s smallest TV antenna.

  9. Different Techniques For EM Design And Verification Of Large And Complex Structures: Industrial Case Studies
    4/25/2017

    New technologies in sensor design (AESA) and the need for integrated structure design to meet increasingly stringent RCS requirements require a new approach to design challenges, and the development of dedicated tools for analysis and processing.

  10. Multicast ABR, DVB-S2X, GSE, Time Slicing: Enabling Cost Effective Delivery Of Live Video Streams Via Satellite
    4/24/2017

    Many satellites are used to provide infrastructure for live broadcasting to large geographical areas. However, the bandwidth resources are expensive and unfit for delivering unicast content, which requires resources that grow linearly with the number of users, making the use of satellites seem an impractical solution. This, however, is not true with the latest satellite transmission progress (DVB-S2X and its ingredients) and a multicast approach. This white paper explains how satellites may be used to deliver live content to a wide range of connected devices in a way that is transparent to the existing components through the use of to Broadpeak’s technologies and TeamCast’s up-to-date features of satellite products.
