5G Breakthrough? Samsung Develops mmWave Adaptive Array Transceiver
Even though true 4G cellular is yet to arrive, Samsung claims to have already taken a major step toward 5G with the development of a new millimeter-wave adaptive array transceiver. The device, which operates in the Ka band (28 GHz), achieves data transmission speeds of up to 1.056 Gbit/s over distances of up to 2 km.
The Sequester, DARPA, And A New Reality For U.S. Defense R&D
Sequestration was the dominant theme at SPIE Defense, Security, and Sensing (DSS) 2013 in Baltimore last week. Talk of U.S. budget cuts and their impact on the defense industry was almost omnipresent during the event, starting with Monday’s plenary keynote address by DARPA Director Arati Prabhakar, who explained how the agency will approach the development of new military capabilities amidst both fiscal and threat uncertainties.
Microwave Ablation Devices Heating Up, But Competition Looms
Over the past several years, microwave ablation has established itself as the medical procedure of choice for the treatment of cardiac arrhythmias and liver, prostate, kidney, lung, and other forms of cancer. However, it doesn’t appear as though the microwave ablation device market will rest on its laurels. If recent research reports and news coverage of novel applications are any indication, the technology is poised for significant future growth.

How To Localize Interference In The High Frequency Range Using smartDF®
Are you impacted by an illegal transmitter? …or a legal transmitter not operating within specifications? … or an industrial controller causing fizzle on an adjacent band? … or just crackle from a poor contact in the building’s wiring?
New fabrication techniques that improve performance, lower assembly costs, or reduce size are always of interest.
Advances in modern radar systems include specialized active antennas, microwave circuits and devices, agile beam steering and shape, and digital space-time signal processing. While the pace of radar technology continues to march forward, two fundamentals remain constant. The first is that the electromagnetic properties of antennas, radomes, and the installation platform are governed by the underlying and unwavering physics.

The morning of December 4, 2011 began normally for the team of Air Force technicians. As they settled into their shift flying unmanned aircraft over Afghanistan, perhaps they chatted casually and swapped stories from the weekend. Very soon, however, their conversations were interrupted by shrill alarm sirens blaring from their control monitors. The video screen on the wall, which normally displayed real-time video imagery from their stealth RQ-170 drone, was now completely black. By Michael Clonts, Product Manager, RT Logic
The introduction of GaN as a solid state semiconductor material has enabled the manufacture of high-power, efficient amplifiers in a small volume. In 2011, CPI developed a 1300-watt S-band solid state power amplifier, CPI model VSS3607. This paper will present details of the design and performance data for the VSS3607 amplifier, including results from a 1000-hour life test.
RF Switch Matrix/Signal Conditioning Challenge: Reverse Engineering And Updating Your Legacy Test System
Almost every company has an old test system in the corner of their lab that provides a test capability that they require. Perhaps it is related to a government program or a commercial product line that has been around forever. Sometimes the system has been mothballed and they need to get it to run again. This is the third in a series of guest columns by Bob Alman of SenarioTek.
Military Satellite Trends And Outlook: Part 1
The use of space is increasing and becoming an essential component for infrastructure in communications, navigation and timing, agriculture and weather monitoring, and disaster relief efforts. From a military perspective, space assets provide necessary resources to support troops, including the provision of imagery, supporting communications, improving targeting, and conversely reducing collateral damage. As a force multiplier, space assets can provide advanced capabilities and compensate for reductions in other conventional assets.

World's Smallest Bluetooth Location 'Stickers', StickNFind, Locate Misplaced Items From Smartphone App Using Nordic Semiconductor nRF51822 SoCs
Ultra low power (ULP) RF specialist Nordic Semiconductor ASA recently announces that its multiple award-winning nRF51822 SoC ('System-on-Chip') has been specified into the world's smallest Bluetooth low energy coin-sized location stickers, 'StickNFind' by Stick-N-Find Technologies. StickNFinds are the size of a U.S. quarter at just 0.98-inch (24mm) in diameter and 0.16-inches (4mm) thick. Users can easily track up to twenty location stickers on a smartphone app. Stickers can be used to track keys, remote controls, pets, and even people. Using a free smartphone app users can locate their stickers using a 'radar screen', set distance alerts called 'virtual leash', and more.
New Method Proposed For Detecting Gravitational Waves From Ends Of Universe

SpotterRF Provides ‘Eyes’ For Mobile Force Protection Training At Camp Williams
The United States spends $1.2 million to send one soldier to serve in Afghanistan for one year*. To protect these warfighters, SpotterRF worked with Camp Williams, Utah in recent exercises to train operators on the use of a compact radar system that cost less than $30,000 with only a 3lb battery and laptop that automatically detects and tracks multiple threats anywhere in a 150-acre area through all weather conditions, night or day. The exercise tested SpotterRF’s effectiveness in conjunction with existing U.S. Army advanced listening systems.
