AIR802 has introduced model LPNFNF06, a new N female to N female coaxial lightning arrestor or surge protector supporting 0 to 6 GHz. Unlike typical protectors, this corrosion-resistant model is tri-metal-plated to minimize intermodulation distortion (IMD). Additional features include a 90 VDC breakdown voltage, 0.5 dB low insertion loss at 6 GHz, 50 ohm impedance and maximum … [Read more...]
Common Mode Filters Feature Integrated ESD Protection
NXP Semiconductors has announced the availability of a new family of common mode filters with integrated ESD protection for high-speed MIPI D-PHY and HDMI interfaces. The new PCMF series offers a typical common mode rejection of more than 12 dB in the band between 300 MHz and 8 GHz. The PCMF2DFN1 (for two differential line pairs) and the PCMF3DFN1 (for three line pairs) are … [Read more...]
Man-Made Electromagnetic Noise Disrupts Bird Navigation
Scientists have known for decades that migratory birds orient themselves using the Earth’s magnetic field in order to fly in the right direction. Now, German researchers have documented for the first time that man-made electromagnetic radiation interferes with these birds' internal compasses. The phenomenon was discovered by Henrik Mouritsen, a professor of neurosensory … [Read more...]
Genetic Approach Yields New Broadband Metamaterial
Researchers have created a specially-formed material using genetic algorithms they say could shield objects from detection by infrared sensors, protect instruments and be modified to cover a variety of wavelengths. "The metamaterial has a high absorption over broad bandwidth," Jeremy A. Bossard, postdoctoral fellow in electrical engineering at Penn State, said. "Other screens … [Read more...]
Data Centers Vulnerable to EMPs, Say Experts
Data centers, used to house computer systems and associated components such as telecommunications and data storage systems, store everything from classified government information to personal photos posted on social media websites. Designers must consider a number of key factors when constructing a data center facility, including site selection, mechanical and electrical … [Read more...]
Integrated Chokes Feature Reduced Footprint and Increased Efficiency
Pulse Electronics Corporation has announced the release of the PA4040 series of chokes, which integrate a common mode (CM) and differential mode (DM) choke into the same component. According to the company, combining two separate magnetic components into a single integrated component reduces power losses across the EMI filter portion of the power supply because it reduces the … [Read more...]
Wideband 2.2 GHz to 7.6 GHz Coaxial Lightning Protection for LTE, Wi-Fi and WiMAX Applications
NexTek, Inc., a provider of lightning protection and EMC/power conditioning products and services, has released a new line of SurgeGuard quarter wave stub lightning protectors. Designed for Wi-Fi, WiMAX, satellite, LTE and ISM applications, the QWS600 series exceeds 802.11, UNII, ISM and MIL-STD-202 standards for usage between 2.2 GHz and 7.6 GHz. Measuring only 63.9 mm … [Read more...]
EMI Shielding Compounds for Automotive Radar and Sensing System Components
Thermoplastics compounder RTP Company has developed new EMI shielding compounds ideal for replacing metal or conductive coated plastic housings in automotive sensing systems. Automotive radar and sensing systems designed to maintain vehicle safety and reliability require EMI protection to eliminate “noise” that could interfere with signal processing, the company says. As the … [Read more...]
Power Lines to Help Map Space Weather
A one-to-two-year pilot project scheduled for launch later this year will utilize U.S. high-voltage power lines as a means to better understand solar events that threaten the electric grid. Led by heliophysicist Antti Pulkkinen of NASA's Goddard Space Flight Center in Greenbelt, Md., the research team will use scientific substations installed under high-voltage power … [Read more...]
Broadband Limiting Amplifiers for Electronic Warfare and Broadband Communications
Pasternack Enterprises, Inc., has released new wide dynamic range broadband limiting amplifiers for use in electronic warfare, microwave receivers and broadband communications systems. Covering a wide frequency range of 1 to 18 GHz, these broadband limiting amplifiers are used to protect sensitive microwave receivers by “limiting” excessive input power, which could potentially … [Read more...]
