Würth Elektronik has released a new miniature chip bead ferrite in the standard 0201 chip format. According to the company, this package design increases packing density of components on circuit boards three-fold compared with the chip bead ferrite packages previously available on the market. Ideal for mobile devices, the new chip bead ferrites offer broadband interference … [Read more...]
IEC 61558-2-10:2014 – Safety of Transformers, Reactors, Power Supply Units and Combinations Thereof – Part 2-10: Particular Requirements and Tests for Separating Transformers with High Insulation Level and Separating Transformers with Output Voltages Exceeding 1,000V
The International Electrotechnical Commission (IEC) has published IEC 61558-2-10 ed1., "Safety of Transformers, Reactors, Power Supply Units and Combinations Thereof - Part 2-10: Particular Requirements and Tests for Separating Transformers with High Insulation Level and Separating Transformers with Outpit Voltages Exceeding 1,000V." The standard is available in the IEC’s … [Read more...]
Researchers Make Flat Surface Behave Like Spherical Antenna
Researchers from Southeast University in China have created a new artificial surface that can bend and focus electromagnetic waves similar to an antenna. The achievement, which the team is calling “the first broadband transformation optics metasurface lens,” could lead to the creation of new types of antennas that are flat, ultra low-profile or that conform to the shape of … [Read more...]
Low-EMI Oscillators with 1.9V Supply Voltage
Saelig Company, Inc. has introduced the new 18HM series oscillators to the Euroquartz range of spread spectrum low-EMI oscillators. The low-cost oscillators offer the significant advantage of reducing EMI at the source— the system clock oscillator—removing the need to employ costly shielded backplanes, ferrite cores and similar techniques to reduce EMI. Featuring a supply … [Read more...]
Software for Installed Antenna Analysis Receives Update
Delcross Technologies has announced version 4.0 release of its Savant software for modeling the installed performance of antennas on electrically large vehicles. New features in this release of Savant include multi-bounce edge-diffraction rays that improve accuracy by modeling antenna interactions with shadowed portions of the platform, an integrated workflow with CST STUDIO … [Read more...]
Medium Power Broadband Amplifiers Up to 18 GHz
Pasternack Enterprises has introduced ten new 1-watt and 2-watt broadband amplifiers for defense, EW/ECM, radar, test instrumentation, telecom, satcom, microwave radio and industrial applications from 2 GHz to 18 GHz. The new broadband RF amplifiers feature a hybrid microwave integrated circuit design and advanced GaAs pHEMT technology for excellent performance. The … [Read more...]
Gigabit Wireless Research Could Open Door to Higher Data Rates
New research on gigabit wireless communications from the University of Bristol in the U.K. could have significant implications for the future of mobile devices. Two research papers presented at IEEE Wireless Communications and Networking Conference (WCNC) in Turkey last week focused on the millimeter-wave band (58-63GHz), in which the researchers believe short-rage gigabit … [Read more...]
Wi-Fi ‘Carpool Lane’ Approach Could Triple Data Speeds
Qualcomm has announced plans for a new technology it said could triple Wi-Fi speeds in homes, offices and in crowded public network areas. Currently, all devices within a certain area compete for a finite amount of bandwidth. This competition often results in slower services for all users, especially in crowded urban areas where more devices are trying to access the sme … [Read more...]
U.S. Navy to Demonstrate Electromagentic Railgun at Sea
The U.S. Navy has announced plans to test a prototype electromagnetic railgun aboard a high speed vessel in 2016. The test will mark the first time an electromagnetic railgun has been demonstrated as sea. Capable of firing projectiles at seven times the speed of sound, railgun technology uses an electromagnetic force known as Lorentz force to rapidly accelerate an object … [Read more...]
Facebook Drones and Satellites to Deliver Global Internet
Facebook Inc. is developing a plan to deliver global Internet access using satellites, drones and other technology. Known as the Facebook Connectivity Lab, the project was announced late last month by Facebook CEO and founder Mark Zuckerberg, who aims to provide affordable Internet services to “every person in the world.” Currently, more than half of the world’s population is … [Read more...]
