Electronics distributor Farnell element14 is now offering RFI shield clips from manufacturer Harwin, which improve the process and reduce the cost of attaching shield cans to PCB by eliminating the need for post reflow solder operations. Typically, to protect sensitive electronic circuits from extraneous EMI/RFI, shielding is mounted to the PCB using through-hole solder tails … [Read more...]
Stamped Spring Pin Socket for Electronic Filter Testing
Ironwood Electronics, a provider of high performance test sockets and adapters for both engineering and production use, has released the CBT-QFN-7033, a new stamped spring pin socket addressing high performance requirements for testing DFN6 electronic filters. “To test electronic filters, a high performance contact is needed,” the company said. “The contactor used in … [Read more...]
The Duke of Kent Visits MILMEGA
The Duke of Kent visited MILMEGA Ltd. earlier this week, in recognition of the company winning the Queen’s Award for Innovation in late 2012. The Duke toured the factory, stopping frequently to talk with MILMEGA staff involved in product design, manufacturing and testing. Andy Kozakewycz and Richard Hazeldine enjoyed lively technical discussions with the Duke regarding the … [Read more...]
Metamaterial Power Harvester Boasts Solar Cell Efficiency
Researchers at Duke University’s Pratt School of Engineering in North Carolina have created a power-harvesting device that can be tuned to capture energy from various sources, including satellite, sound and Wi-Fi signals, and convert it to direct current voltage capable of charging small electronic devices. While the new device is not the first “energy-harvester” ever created, … [Read more...]
New Type of Filter May Help Bring Order to Crowded Radio Spectrum
Scientists from the Netherlands have developed a new type of filter based on micromechanical resonators they say is ideal for maintaining order amidst the expected future growth of frequency standards. According to researchers at the MESA+ Institute for Nanotechnology at the University of Twente, the new solution consists of two mechanical resonators that vibrate at an … [Read more...]
New Generation of PCB Insertion Loss Test Systems Introduced
Polar Instruments, a developer of signal-integrity tools for PCB design, fabrication and test, announced earlier this week that its next-generation Atlas PCB insertion-loss test system will be available for preview November 12-15, 2013 at Productronica in Munich, Germany. Atlas 2014 introduces a new generation of the company’s PCB insertion-loss test systems, combining the … [Read more...]
New Tunable Dielectric Material May Push Capacitor Performance
An international team of researchers based at Cornell University in Ithaca, N.Y. has announced the creation of a new tunable dielectric material—an insulator whose ability to store electrical charge changes when a voltage is applied—they say could benefit capacitor performance in smartphones and other electronic devices. “This is a radically different material compared to what … [Read more...]
Redesign Extends Portable Antenna Test Lab Capabilities
Microwave Vision Group’s StarLab, a compact and portable multi-purpose antenna test lab, has been enhanced with new capabilities and a new design. According to the company, the StarLab has undergone a complete transformation to give it extended capabilities as well as a new look for an improved user experience. The new StarLab now covers frequency bands as low as 650MHz and up … [Read more...]
Field Strength Meter Evaluates Wind Turbine Effects on Radar Systems
German researchers have developed a device to help evaluate the potential for interference between wind turbines and radar instruments. Designed for suspension from a helicopter or small unmanned aerial vehicle (UAV), the device measures the strength of the electric field and the radar signals used in meteorology, defense or air traffic control, reports the Institution of … [Read more...]
Simulation of GHz Insertion Loss Components; Cross-Section Geometry Influence on Conductor Loss
Tracey Vincent Application Engineer, CST ABSTRACT To attain realistic estimations of simulated insertion loss, all insertion loss components need to be considered and accounted for. In particular, the dielectric and conductor loss components can require careful material parametrization in order for 3D simulated loss to be realistic. An overview of these parametrizations is … [Read more...]
