Thin film interconnects are a standard circuit technology used in high frequency design components and subsystems where transmission line widths of .005" and under are critical to performance as well as high power applications where thermal conductivity is of concern and materials such as beryllium oxide and aluminum nitride...

The development of Soldier Modernization Programs (SMP) across NATO and other countries poses challenges — not only through the extension of voice and data communications down to each infantryman, but the parallel need to define the level of security required to protect the information sent. Communications security for individual...

Lamberto Raffaelli President and CEO LNX Corp. MWJ: What are the roles of microwave technologies in light of current requirements for lighter, more deployable forces? How are these roles different from microwave technologies employed in the Cold War Era? LR: Certainly, in the recent past, our defense customers have...

M/A-COM is now offering new lightweight cable assemblies utilizing the FN34RXLW cable, a lightweight version of its proven FN34RX cable assemblies. This new product offering is intended for use in high performance military airborne applications. All popular assembly configurations are readily available with reduced mass at competitive prices. Weight...

The European Southern Observatory (ESO) is an intergovernmental European organization for astronomical research, coordinating many projects. The leading one in radio astronomy is the construction of the Atacama Large Millimeter Array (ALMA), 1,2 a project for an interferometer aimed at the study of microwave and sub-millimeter signals coming from...

Four earthquakes and a tsunami warning not withstanding, the IMS 2005 Symposium and Exhibition in Long Beach, CA turned out to be a huge success. Cool ocean breezes and hazy days were the norm outside, while crowded technical sessions and a busy show floor were the norm inside the...

This article covers the basic concepts of antenna measurements, including definitions of the reactive near-field, radiating near-field and radiating far-field; primary antenna measurement parameters; and the various types of antenna measurements, including pattern, gain and polarization measurements. The most common types of measurement range configurations are detailed, including far-field...

In modern society, electronic systems impact significantly on everyday life, for individuals, commerce, industry and the community as a whole. Their safe and reliable operation is generally taken for granted, as is the humble surge protector that plays such a vital role in maintaining transceiver structures and ensuring the...

A series of high frequency relays has recently been developed that feature very small size and low power consumption. The most recent relay in this series is the model G9YA, a 26.5 GHz coaxial relay designed primarily for mobile communications base station and antenna applications. The new single-pole, double-throw...

Wireless technologies have developed in a way that can best be described as ‘unbelievable.’ Global mobile subscriptions rose to 1.7 billion in 2004 and the number continues to grow at a healthy pace. Furthermore, the production volumes of cellular phones are remarkable when compared to other consumer products —...
