  1. How Connectors Perform In Harsh Corrosive Environments
    8/11/2017

    It is important to understand the main factors driving corrosion, and how to make the best interconnection choices for a long-lasting and reliable solution. This white paper discusses the key factors in selecting the best connectivity options for even the most robust and corrosive application environments.

  2. PNT: Going Beyond GPS
    5/19/2017

    As powerful as GPS technology is, it has three key problems. To overcome these problems, new positioning, navigation, and timing (PNT) systems are being developed that can enhance the effectiveness of existing GPS, and take advantage of alternatives to conventional GPS.

  3. The Effect Of Low-Quality Antennas On Network Backhaul
    6/11/2016

    When designing a network backhaul, the finest technology is considered for the active components, while the importance of passive components is often taken for granted. The antenna has been regularly seen as a cost-saving component where concessions can be made on quality. 

  4. Radar Waveforms for A&D and Automotive Radar
    4/18/2016

    This white paper provides a more detailed view on radar waveforms for Aerospace and Defense and commercial radar systems. Waveforms such as pulse and pulse-Doppler signal, continuous wave and frequency shift keying waveforms are described. 

  5. Doppler Generation For Moving Target Testing
    2/2/2015

    Channel Environment Replicator (CER) applications simulate and recreate outdoor environments in which radar systems must operate. It’s a much less expensive testing method when compared to the potential complications encountered in more traditional field testing, though testing a moving target in such an application isn’t all that simple.

  6. Radar And Radio Range Simulation Using FODL
    2/2/2015

    FODL (fiber optic delay line) systems eliminate the need for expensive and time-consuming outdoor range tests for radio and radar systems. This white paper outlines how FODL systems’ accuracy, repeatability, and reliability can save money and time when conducting these tests and also explains for delay line core technology works.

  7. A New Approach To Wireless Broadband Technology For IoT
    1/31/2014

    Wi-Fi has been incredibly successful in making wireless broadband communication ubiquitous among mobile computing devices like laptops and smart phones. Wi-Fi’s cost-effective, IP-based flat architecture (i.e. a simple wireless extension to Ethernet) is a primary contributor to this success. A positive spiral of R&D investments and manufacturing scale and efficiencies are pushing Wi-Fi’s price-performance ratio to unprecedented levels. This trend will continue for the foreseeable future.

  8. Overcoming Gain Slope Issues In Microwave Modules
    1/21/2014

    If you are a microwave hardware engineer, you most likely have had a few sobering experiences when testing your new design the first time. This is particularly true for wideband high frequency modules — they almost never look like the model.

  9. The Design Of Ultra Narrow-Band Amplifiers Using Small Signal Varactor Up-Converters For ESM, ECM, ECCM, And ELINT Applications
    1/17/2014

    A method is presented in this paper for realizing tunable amplifiers with bandwidths of less than 0.5%; without the use of superconductors and cryogenic cooling. This method uses a small signal varactor up-converter to achieve these ultra narrow bandwidths. 

  10. Enhancing Link Network Performance In Tactical Communications
    1/17/2014

    In tactical communications the link networks are the critical layer that connect brigade command posts and various operational units such as artillery and combat battalions together. The Combat Net Radio (CNR) systems provide communications for the front line troops equipped with portable and vehicle installed radio equipment allowing information and command messages to be relayed between the command centers and the operational units. However, seamless connectivity between the CNR network and the link network cannot be always provided due to incompatibility and limited functionality of equipment available.
