The MLCCs reduce signal loss and energy consumption in power amplifier modules, VoIP networks, cellular base stations, GPS … [Read more...]
FCC to Review Mobile-Phone Radiation Safety
The U.S. Federal Communications Commission plans to ask whether its standards protect people from mobile-phone radiation, a question it hasn’t posed in 15 years, as people use smartphones for longer, more frequent calls. A formal enquiry would review the FCC’s standards with the concerns of more frequent use, longer-use, new mobile-phone technology, and use by children in … [Read more...]
New Point-to-Point Interface that Reduces EMI & RFI in LCD Panels
Parade Technologies Ltd. has announced a new type of point-to-point high speed interface for use within LCD display panels. The new Scalable Intra Panel Interface, or SIPI™, achieves high data rate, low power use, and reduced interference with embedded system wireless services to meet the challenging demands for ultra-thin, high pixel density mobile displays. SIPI provides … [Read more...]
Team Finds New Cell Phone Possibilities in Untapped Terahertz Range
Researchers at University of Texas Dallas have designed a chip that could turn mobile phones into an imaging device capable of “seeing” through walls, wood, plastics, paper and other objects. The team used previous research completed on the terahertz band of the electromagnetic spectrum and new advances in imaging technology to design the chip. Learn more from UT … [Read more...]
Swiss Researchers: EM Radiation Can Indicate Keystrokes and Can Compromise Privacy
According to research carried out by doctoral students Sylvain Pasini and Martin Vuagnoux working in the Security and Cryptology Laboratory at the Ecole Polytechnique Fêdêrale in Lausanne, Switzerland computer keystrokes can be detected from afar by detecting slight changes in the electromagnetic radiation emitted by the keyboards. They concluded that keyboards should not be … [Read more...]
Fundamentals of EMC Design: Our Products Are Trying To Help Us
INTRODUCTION We often design electronic products only to find that when we test them for electromagnetic compatibility (EMC), their emissions and/or immunity are not as good as we need them to be. Usually, at this time, we feel as if we are fighting against the laws of physics to contain the conducted and radiated emissions, or to reduce susceptibility. But in fact the laws of … [Read more...]
UL Standard on Filters Helps Provide Assurance on Safety Issues
Arguably the two biggest offenders in custom electronics hyperbole are the cabling and power conditioning/surge suppression categories. Other than power cables, the topic of cabling safety has always been innocuous because of the products’ low-voltage characteristics. Taking the safety issue to the next level, however, are power conditioner/surge suppressor components that are … [Read more...]
High Density Embedded Capacitance Material
3M announced the availability of its Embedded Capacitance Material (ECM), which allows design engineers a new way to greatly improve power integrity and reduce electromagnetic interference (EMI). The newest offering of 3M’s ECM material will provide one of the highest capacitance density and halogen-free solutions on the market. This helps design engineers provide hi-fidelity … [Read more...]
Coaxial Communication Cables Standard
IEC 61196-8-1:2012 is part of the IEC 61196 series and applies to coaxial communications cables described in IEC 61196-8. It specifies the requirements for semi-flexible radio frequency and coaxial cables with polytetrafluoroethylene (PTFE) dielectric. These cables are for use in microwave and wireless equipment or other signal transmission equipment or units at frequencies … [Read more...]
Measurement Suite for WLAN 802.11ac Devices
Aeroflex Limited is adding 802.11ac support to its PXI 3000 Series test system to facilitate the worldwide growth of 802.11ac Wireless Local Area Network (WLAN) mobile devices.Wireless devices using the 802.11ac standard will boast a 6X increase in network speed over 802.11n. The 802.11ac devices are faster because they use a less congested portion of the radio frequency (RF) … [Read more...]
