B&K Precision has introduced an addition to its 9115 Series with the new multi-range programmable DC power supply—model 9117. The new 9117 can deliver up to 3000 W of output power in any combination of voltage up to 80 V and current up to 120 A within its power rating. It offers twice as much output power as current models in the 9115 series and has a 2U 19" rackmountable … [Read more...]
GaN Coaxial Power Amplifiers
Pasternack recently launched its increased offering of gallium nirtride (GaN) coaxial power amplifiers. “The high power density of gallium nitride semiconductor technology dissipates heat more effectively which results in amplifier designs that have significantly higher output power levels over broadband and narrowband frequencies,” according to the company. This technology … [Read more...]
New Metamaterial Yields Invisibility for Aircraft and Drones
Electrical engineers from the University of California have created a new ultra-thin metamaterial that could provide a cloaking device and make UAVs (Unmanned Aerial Vehicles) invisible. The new material creates invisibility and leaves no electronic, infrared or visual signatures for enemies to detect. The new design uses “an ultra-thin Teflon substrate, studded with … [Read more...]
Woman Claims Wi-Fi Causes Illness; French Court Grants Disability Allowance
A French court has granted Marine Richard, a woman who claims she is ‘allergic to Wi-Fi,’ £500 a month (about $764 U.S. dollars) in disability allowance. Richards claims she suffers from electromagnetic sensitivity and that exposure to Wi-Fi, mobile phones and televisions cause her extreme pain. According to Richard’s lawyers, she has been living away from society in a barn in … [Read more...]
RF Filter Ideal for Use in Intelligent Transport Systems

3D Printing Can Add Circuitry
Researcher Michael Perrone is currently testing a prototype of one of the world’s most advanced 3D printers, which was built by a startup company known as Voxel8. The 3D printer is not on the market yet, but it can produce small objects out of plastic while simultaneously adding circuitry to them. The printer was produced last month in a lab at Harvard University. During … [Read more...]
High-tech Highways Could Charge Electric Cars While Driving
The United Kingdom is currently testing technology that would allow high-tech highways to recharge electric cars as users are driving. “The U.K. has already tested a bunch of different approaches to this technology and identified versions that work and are ready to manufacture. In basic terms, the system has power lines connected to coils under the surface of a road, which … [Read more...]
Parents Sue Boarding School over its Wi-Fi Signal
Parents are suing Fay School, a boarding school in Southborough, Mass., over claims that the school’s Wi-Fi signal is making their 12-year-old son sick. According to the Worcester Telegram & Gazette, the parents claim their son has ‘Electromagnetic Hypersensitivity Syndrome’ and has suffered from nausea, nosebleeds and headaches since the school activated a stronger … [Read more...]
High Power Coaxial Limiters Handle up to 200 Watts
Fairview Microwave Inc. announces a new family of broadband, high power coaxial limiters that protect sensitive components and RF receivers that are close to high power signals. Depending on the model, the limiters operate on frequencies ranging from 0.5 GHz to 40 GHz. The limiters also offer seven different design options, a low leakage power of 10 to 15 dBm and limited … [Read more...]
Multi-Domain Computer Networking Solution Introduced
Advanced Programs Inc. (API) introduces a new Multi-Level Security Platform (MLSP). The MLSP allows the user to access up to four separate security domains in one desktop platform and it consists of four separate CPUs.
