ProductsRF Amplifier System
Empower RF Systems (Inglewood, CA) has begun shipping the Model 2180 RF amplifier system covering 1 to 2.5 GHz and delivering 2 kW CW of broadband output power in a 8U, air-cooled chassis. Features include: user selectable configuration and operation in three different modes - AGC (Automatic Gain Control), ALC (Automatic Level Control) and MGC (Manual Gain Control); modern and multi-faceted Monitoring and Control (M&C) user interfaces, including a Web browser, TCP/IP Ethernet, RS-485 interface and a front panel touchscreen display (optional IEEE-488 GPIB interface available); and enhanced ruggedness using the latest in high voltage RF transistors (GaN).

12A POL DC-DC Converters
TDK Corporation (National City, CA) has introduced the 12 Ampere TDKLambda iCH series of POL (Point of Load) non-isolated DCDC converters. Accepting a wide range input of 4.5 to 14 VDC, the series can operate from either a 5 VDC or 12 VDC bus. The iCH series can provide output voltages from 0.7 to 8.5V, with efficiencies of up to 97%. A low internal power loss allows the iCH to deliver 12A output current, without forced air cooling, in ambient temperatures in excess of 70 °C.
AdvancedTCA Chassis
Pixus Technologies (Waterloo, Ontario, Canada) now offers a 15U AdvancedTCA (ATCA) chassis that exceeds 400W/slot cooling capability and meets stringent NEBS requirements. The Pixus chassis leverages the original Kaparel design that used patented Ri- Cool II blowers for 275W/slot of cooling. Today’s 15U unit provides more air evacuation using the next generation of reverse impellar hot-plug cartridges. The new RiCool III blowers feature 185 CFM of airflow per fan with 71mm H20 of static pressure.
Armed Forces Are Developing Laser Weapons
Responding to lawmakers' questions about how close the Army is to developing offensive and defensive directed-energy weapons, Mary J. Miller responded: "I believe we're very close." Miller, deputy assistant secretary of the Army for Research and Technology, testified before the House Armed Services Committee's Subcommittee on Emerging Threats and Capabilities recently regarding the Army's Science and Technology (S&T) Program for fiscal year 2017.
Electric Patch Holds Promise for Treating PTSD
An average of 30 years had passed since the traumatic events that had left them depressed, anxious, irritable, hypervigilant, unable to sleep well and prone to nightmares. But for 12 people who were involved in a UCLA-led study — survivors of rape, car accidents, domestic abuse and other traumas — an unobtrusive patch on the forehead provided considerable relief from post-traumatic stress disorder.
Researchers Design Bat-Inspired Wings for Micro Air Vehicles
Researchers from the University of Southampton have designed innovative membrane wings inspired by bats, paving the way for a new breed of unmanned Micro Air Vehicles (MAVs) that have improved aerodynamic properties, can fly over long distances and are more economical to run.
Robotic Falcon Captures and Retrieves Renegade Drones
Michigan Technological University is developing a drone catcher that could pursue and capture rogue drones that might threaten military installations, air traffic, sporting events — even the White House. It’s a deceptively simple system: a launcher that shoots a big net attached to a large drone by a string. The system can be autonomous, controlled by a ground-based human pilot, or a combination of the two.
Cockroach-Inspired Robots Open Doors for Military Missions
Supported by the U.S. Army Research Laboratory, University of California-Berkeley researchers have developed a small, crawling robot that mimics a cockroach's ability to squeeze through confined spaces. These spaces include rubble generated by natural disasters and explosions that first responders may not be able to access in emergencies.
“Second Skin” Protects Soldiers from Chemical and Biological Agents
The U.S. Army Natick Soldier Research, Development and Engineering Center is working with the Massachusetts Institute of Technology, the University of California at Santa Barbara, the Air Force Civil Engineering Center, and the U.S. Army Edgewood Chemical Biological Center to develop second skin, the next generation of chemical-biological protection for the warfighter.
