  1. Report -- Electronic Warfare: The Changing Face Of Combat
    9/25/2008
    Electronic Warfare (EW) is the struggle for control of the electromagnetic spectrum — to assure that friendly forces can use the spectrum to their full potential in wartime, while denying that use to enemies. U.S. military success depends on unfettered access to the spectrum to enable electronic equipment such as radars, communication links, computer networks, and sensors to work. The purpose of this report is to discuss the challenges and opportunities facing electronic warfare today and recommend steps to secure a durable and viable electronic warfare capability for the future.

  2. Say What? My Cross-Talk Problem Is At The Component Level? A Filter, You Say?
    9/19/2008
    The devil is in the details. For system engineers who work for U.S.-based manufacturers of RF and microwave products, that seems to be the message they are painfully discovering. As their products get rushed into the marketplace and put to the test by wireless service providers and consumers, shortcomings in frequency management come home to roost in the form of noise, cross-talk, signal dropouts and even complete transmission interruption. While the product design holds up under scrutiny on paper, test engineers are increasingly rooting out the source of the problem, and oftentimes the solution turns out to be one single component: the filter.

  3. Guest Column: Time Matters — How Power Meters Measure Fast Signals
    9/8/2008
    Modern wireless and cable transmission technologies, as well as radar systems, present demanding challenges for device and system developers. Manufacturers of test and measurement equipment are driven to offer products that fully support today’s needs, while anticipating the requirements of future technologies. Accuracy has always been a critical requirement in the test and measurement world, but modern technologies demand another must-have — highest data acquisition and processing speeds to allow accurate measurements of complex signal waveforms. This article describes the different techniques RF peak power meters employ to meet these challenges

  7. Millimeter-Wave Printed Circuit Board Developments - Improvements For Mechanical Packaging And Electrical Requirements
    8/18/2008
    Millimeter applications place heightened and unique requirements on circuit board laminates used as transmission lines or as antennas. Historically, applications were low volume. Recent growth of millimeter applications, such as ACC (adaptive cruise control) and side lane changing sensors for standard, high volume, affordably priced vehicles, or commercial millimeter communication systems, has driven circuit board laminate fabricators to innovate materials. This article explores advancements in millimeter-wave circuit boards and the technical requirements placed on materials.

  9. Improvements In Microwave Laminates For Amplifier Reliability And Efficiency
    8/18/2008
    Trends in the electronic industry continue to drive materials to satisfy higher power and higher thermal stability requirements. Many techniques have been developed to improve heat rejection in electronics, including engineered heat sinks, thermal interface materials, and whole subsystems (cooling fans and heat pipes). This pursuit has extended to RF and microwave circuit board substrate materials.
  10. Antenna Performance Basics
    8/13/2008
    The antenna is an important component of a wireless network. The proper antenna can optimize the range and reliability of a radio network while the wrong antenna causes high-performance wireless devices to appear to stop operating. This article provides a basic knowledge of key performance characteristics used to analyze antenna performance within installation environments.
