The EClamp237xK family of resistor-capacitor (R-C) protection devices from Semtech Corporation safeguards lines for cellular frequencies between 1.8 GHz and 2.5 GHz, the data rates required by the latest generation of high-resolution LCD screens used for visually oriented 3G handsets. This series includes the four-line EClamp2374K, the six-line EClamp2376K and the eight-line … [Read more...]
NIST Develops Electromagnetic Phantom for Testing Metal Detectors
The National Institute of Standards (NIST) has developed an electromagnetic “phantom”—a carbon and polymer mixture that simulates the human body—that is intended to improve and standardize the testing of walk-through metal detectors. Currently, detectors are tested using human volunteers carrying various metallic objects or pieces of plywood on which the objects are mounted. … [Read more...]
Norwegian Firm Launches Purpose-Built EM Survey Vessel
Trondheim, Norway-based sea-logging firm Electromagnetic Geoservices ASA (EMGS) has launched the BOA Thalassa, a purpose-built vessel that employs EMGS’ proprietary technology to support oil and gas companies in their search for offshore hydrocarbons. Survey capabilities have been substantially increased by the vessel’s ability to handle a record number of receivers. The BOA … [Read more...]

Military COTS Filter Provides EMI Filtering & Transient Protection
The M-FIAM7 from Vicor is a DC front-end module that provides EMI filtering and transient protection. The M-FIAM7 allows designers using Vicor’s 28-V DC/DC V•I Chip modules to meet conducted emission/conducted susceptibility per MIL-STD-461E; and input transients per MIL-STD-1275A/B/D, MIL-STD-704A-F, and DO-160E. The M-FIAM7 accepts an input voltage of 14 to 50 VDC and … [Read more...]
ETSI Technical Report on EMC, Spectrum Use, and Implanted Medical Devices
The European Telecommunications Institute (ETSI) has issued ETSI TR 102 655 V1.1.1, which deals with electromagnetic compatibility and radio spectrum matters. This document defines new requirements for radio frequency spectrum usage for low-power active medical implants and their peripheral radio control systems. The report also proposes a concept that should permit a … [Read more...]
NASA’s Lunar Orbiter Passes EMC and Other Environmental Testing
NASA’s Lunar Reconnaissance Orbiter (LRO) successfully passed EMC testing at the Goddard Space Flight Center in Greenbelt, MD. The orbiter will carry seven instruments to provide scientists with detailed maps of the lunar surface to increase our understanding of the moon’s topography, lighting conditions, mineralogical resources, and natural resources. The spacecraft will spend … [Read more...]
FCC Okays Test of Jamming Devices in DC Correctional Institution
