  1. 5 Common Causes Of Frequency Drift In Crystal Oscillators And Their Solution

    Setting the initial frequency of an oscillator to the most precise values can be frustrating when you realize that the oscillator will not be able to maintain that frequency. This article covers multiple sources of frequency instability.

  2. Combining Near-Field Measurement And Simulation For EMC Radiation Analysis

    Failing a required EMC test at the end of a product design cycle can imply a costly product redesign and drastically set back the time-to-market. This white paper outlines a process that enables required EMC testing to be performed much earlier in the design cycle.

  3. Satellite M2M, The IoT, And The Public Sector

    As machine-to-machine and Internet of Things technologies grow congruent with daily life, satellite-based IoT is increasingly relevant to the mix. Given that IoT devices are primarily used to eliminate the need for human interface, as well as provide real-time automated monitoring and control across distances, it’s often essential to enable its functioning in remote regions that lie outside the range of terrestrial network coverage.

  4. High-Efficiency Front-End For Pico And Modular Large Base Stations At LTE Bands 1 And 7

    The key to improving energy efficiency lies, fundamentally, in the use of active antennas. However, duplex operation of cellular phones greatly distorts the desired performance of active antennas. To correct this, one must deploy self-diplexed antennas.

  5. Is Your Spectrum Monitoring Tool Prepared For Modern Communication Technologies?

    Radio frequency (RF) spectrum is one of the most sought-after resources in the world. In the U.S., public spectrum auctions by the government generate billions of dollars for the right to utilize spectrum bands. 

  6. 802.11ax: 5 Things To Know

    The current Wi-Fi standard, 802.11ac, works very well in a home environment. However, as with previous Wi-Fi standards, it may reach its limits around 2022 when there could be up to 50 nodes in a home. The 802.11ax network is the next evolution in the IEEE 802.11 Wi-Fi standard and will become prevalent in very dense environments, such as urban apartment complexes, college campuses, concert venues, or sports stadiums, where many clients will access the internet over Wi-Fi. This article presents five key aspects of the new 802.11ax network and the next generation of Wi-Fi.

  7. The Future Of E3 And Spectrum Engineering

    In military procurement, the spectrum and electromagnetic environmental effects (E3) considerations are afterthoughts. To enable next-gen military systems and fleet upgrades, we must consider dynamic E3 and spectrum requirement during system development and procurement phases.

  8. RCS of Hellfire Missile Using Remcom's Accelerated X3D Model

    Accurate calculation of RCS at millimeter wave frequencies requires sufficiently detailed geometric representation of the target and physical modeling techniques that capture the scattering effects of small facets.  Highly detailed facet models and traditional methods for calculating RCS at these frequencies can often result in very long run times.  Using Remcom’s X3D with Physical Optics (PO) and Method of Equivalent Currents (MEC) model for calculating RCS, accurate results can be achieved within reasonable run times.

  9. AlGaAs PIN Diode MMICs – Frequency And Power Capability

    Monolithic microwave integrated circuits (MMICs) based on high-power PIN diodes are increasingly used for many transmit/receive systems in advanced defense electronics and telecommunications applications.

  10. What The Rapid Commercialization Of Microwave And mm-Wave Spectrum Means For The Defense Industry

    As 5G technologies bring commercial applications into the microwave and mm-Wave bands, new challenges must be met to provide safety and security to armed forces and civilians alike.
