How much ESD can an IC bear?
IC immunity tests under the influence of ESD Sven Konig Nowadays, electronic devices have to meet the highest standards in terms of ESD immunity. "According to estimates of TÜV NORD, the manufacturing industry incurs costs amounting to millions of euros every year due to electrostatic discharges. ESD effects lead to circuit failures which in turn bring a vehicle, a process or … [Read more...]
RF Reference Sources Simplify RF Calibration
Fluke Calibration has released the 96270A and 96040A low phase noise RF reference sources for RF calibration applications. Designed to help simplify RF and microwave calibration systems by replacing many of the instruments and accessories in existing systems, these new reference sources feature accurate signal delivery direct to the UUT input (up to 27 GHz in the 96270A); an … [Read more...]
4G Study Highlights Need for More Thermal Loss Research
A new study from Danish researchers suggests the ongoing push towards global 4G roaming and high-quality, frequency-reconfigurable antennas will need to account for new loss capacities not considered by previous technology. The worldwide demand for 4G technology and higher data rates in cell phones has led to a new, urgent need for frequency-reconfigurable or tunable antennas. … [Read more...]
Microwave Multi-Tool Steps Towards PROMFA Development
Researchers in Spain and the United Kingdom have developed a resonator element capable of simultaneously acting as both a filter and an antenna in a major step towards the development of programmable microwave function arrays (PROMFAs). The so-called microwave circuit equivalent of an FPGA is a network of microwave hardware that can be reconfigured to take on different circuit … [Read more...]
Researchers Discuss Narrowband EM Absorbers in New Research
While providing an overview of different types of narrowband electromagnetic absorbers, researchers from the Zhejiang University in Hangzhou and the Taiyuan University of Technology in China point out ways to create effective broadband/multiband absorbers with crucial applications in fields like solar-energy harvesting. The review article “Plasmonic and metamaterial structures … [Read more...]
No-Power Wi-Fi Connectivity May Boost Internet of Things
Researchers at the University of Washington have developed a communication system that uses radio frequency signals and repurposes existing Wi-FI infrastructure to supply power and provide Internet connectivity, respectively, to battery-free devices. Known as Wi-Fi backscatter, this technology is the first of its kind capable of connecting battery-free devices to Wi-Fi … [Read more...]
