A one-to-two-year pilot project scheduled for launch later this year will utilize U.S. high-voltage power lines as a means to better understand solar events that threaten the electric grid. Led by heliophysicist Antti Pulkkinen of NASA's Goddard Space Flight Center in Greenbelt, Md., the research team will use scientific substations installed under high-voltage power … [Read more...]
Broadband Limiting Amplifiers for Electronic Warfare and Broadband Communications
Pasternack Enterprises, Inc., has released new wide dynamic range broadband limiting amplifiers for use in electronic warfare, microwave receivers and broadband communications systems. Covering a wide frequency range of 1 to 18 GHz, these broadband limiting amplifiers are used to protect sensitive microwave receivers by “limiting” excessive input power, which could potentially … [Read more...]
Laser Technology Could Divert Lightning Strikes
A new next-generation protection system could remove the need for lightning rods and other mitigation measures by preventing lightning strikes from hitting a building entirely. Researchers at the University of Arizona and University of Central Florida have developed a new technology capable of changing the path of lightning bolts using high-energy laser beams. According to the … [Read more...]
RF Power Amplifier Reference Solution Speeds Test System Development

Signal Amplifier Design for Mobile Phone Masts to Cut Energy Demands
A breakthrough in the design of signal amplifiers for mobile phone masts could cut the load on power stations by 200MW and reduce CO2 emissions by 500,000 tons per year. Researchers from the University of Bristol and the University of Cardiff say the new amplifier, which was funded by the Engineering and Physical Sciences Research Council (EPSRC), works at 50 percent … [Read more...]
More Research into Cancer-Radio Waves Link Needed, Says Canadian Panel
An expert panel reviewing Canadian safety limits for exposure to radio waves has concluded that existing standards appear sufficient and that there is no clear evidence of risks from lower exposure. The independent panel convened by the Royal Society of Canada issued its report Tuesday on Health Canada’s Safety Code 6, which sets limits on exposure to radio frequency fields … [Read more...]
Modeling Tool Speeds Up Computation of EMI on Electronic Circuit Boards
Researchers in Singapore have created a new computer tool they say could speed up the electronic design process by more quickly ensuring electromagnetic compatibility. “Electromagnetic interference is a critical problem for the electronics industry,” Xian-Ke Gao from the A*STAR Institute of High Performance Computing in Singapore said. “Engineers are keen to understand how the … [Read more...]
Power Line Carriers Offer RF Interference Immunity to Utility Substations
AMETEK Power Instruments is offering two power line carrier products that address the growing concern of RF interference caused by the use of 3G/4G "smart" phones and routers in substation environments. According to the company, the new TC-10B/TCF-10B and Universal Power Line Carrier (UPLC) products are protected against changes in performance beyond specified tolerance, … [Read more...]
