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...]

TECH TIDBIT: Insects Controlled by Electromagnetic Waves?
A new video has surfaced on YouTube which shows ants moving in a ring around an iPhone when the phone receives a call – suggesting that the electromagnetic waves emitted from a ringing phone can affect the insects. Researchers are divided on the matter. One Australian researcher, Simon Robson of Queensland's James Cook University, believes the phone has nothing to do with the … [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...]

Power Amplifiers Operate from 17.65-19.75 GHz
Richardson RFPD, Inc. introduces new 2W power amplifiers from MACOM Technology Solutions. The amplifiers were designed for applications in the 18 GHz band such as point-to-point radios and cellular backhaul. The MAAP-011145 amplifiers include a 7mm surface mount, a lead free package and operation from 17.65-19.75 GHz. “The circuit provides 25 dB small signal gain, +43 dBm … [Read more...]
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...]
Company Introduces New Amplifiers at Symposium
TMD Technologies will introduce a new wide range of travelling wave tube amplifiers (TWTAs) for EMC HIRF testing at the IEEE EMC Symposium in Dresden. The TWTAs are compact, lightweight, affordable and offer high field strength. The amplifiers are ideal for use in numerous EMC testing and intermodulationg (PIM) testin applications as well as telecommunications, electronic … [Read more...]
Electromagnetic Catapult Successfully Installed on Aircraft Carrier
The Navy’s new electromagnetic catapult, the Electromagnetic Aircraft Launch System, (EMALS) has successfully been installed on the USS Gerald R. Ford, replacing the steam catapults previously used to launch aircraft. Because EMALS yields less maintenance, more control, more reliability and a lighter weight, the Navy decided it will be used on all future aircraft carriers in … [Read more...]
Proposed Radio Tower Could Cause Health Risks
Washington state residents are against the proposed KRPI radio tower Whatcom County wants to put south of Point Roberts. Residents reportedly fear the radio tower would emit electromagnetic radiation and create serious health risks. “Recent cellular research has shown that our DNA suffers breaks in its strands with continuous exposure to EMR. Continuous exposure to EMR would … [Read more...]
