AMETEK Programmable Power announces it has added the ability to sink and regenerate DC current to its RS and MX Series Power Sources. This new option will significantly reduce operating costs. “The addition of this option to an RS or MX Series power source with AC Sink installed allows users to source and sink both AC and DC currents at up to 100 percent of the source's rated … [Read more...]
Study Reveals Radiation from Solar Events Unlikely to Affect Earth
“In recent years, research has suggested congenital birth defects down on Earth's surface could be caused by these ‘solar particle events’ - spikes in cosmic rays from the sun that touch off the northern lights and sometimes hamper communications or the electric power grid,” according to Science Daily. Even though airplane crews at high altitudes are exposed to harmful levels … [Read more...]
New Waveguide Detectors Cover Frequency Ranges from 26.5 to 110 GHz
Pasternack introduces new high performance waveguide detectors that cover frequency ranges from 26.5 to 110 GHz. The detectors are zero biased and perform the best in KA, Q, U, V, E and W frequency bands. Because the detectors are zero biased, no external DC bias or mechanical tuning is needed. The detectors also offer a rugged steel construction, high thermal stability, … [Read more...]
NASA Captures Four-hour Solar Flare on Video
NASA’s Solar Dynamics Observatory (SDO) captured a solar flare and a coronal mass ejection (CME) on video on June 18. “The SDO has been studying the Sun since 2010 and captured this flare at multiple wavelengths, allowing it to show the ultraviolet light of the massive flare,” according to Mirror Online. The solar flare, which has been named “Spit of Satan,” lasted for four … [Read more...]
High Frequency Waveguide Couplers Operate to 110 GHz
Pasternack introduces a new portfolio of ultra-high frequency directional waveguide couplers that operate up to 110 GHz. The portfolio includes 28 unique coupler models with varying frequency ranges from 18 GHz to 110 GHz in frequency bands K, Ka, Q, V, E and W. Two physical configurations are available: the standard waveguide and split block waveguide. “Both the traditional … [Read more...]
New Radio Telescope Detects Galaxy From 5 Billion Light Years Away
A new radio telescope in Western Australia, known as Australian Square Kilometre Array Pathfinder (ASKAP), has discovered PKS B1740-517 – a galaxy located more than 5 billion light years away. Six of the 36 dishes on the radio telescope captured signals emitted from PKS B1740-517. This discovery demonstrates that ASKAP can detect galaxies and signals that other telescopes … [Read more...]
‘Unstoppable’ New Hacking Device Steals Encryption Keys Out of the Air
A group of researchers from Tel Aviv University and the Israeli research center have produced a new hacking device that can steal encryption keys “out of the air.” The device cannot be stopped by disabling Wi-Fi networks or turning off Bluetooth because the device doesn’t use standard communication methods to steal data. The device uses radio waves emitted from computer … [Read more...]
Connector Series Includes EMI Shielding
Mouser Electronics introduces the Amphenol Pegasus series of twist and lock ‘scoop-proof’ connectors with EMI shielding. “EMI shielding is provided by an electroless copper and nickel plate, and a copper alloy spring finger gasket. Tests show greater than 50db of attenuation for low-end signals (<100Mhz) and greater than 40db of attenuation for high-end signals (<1Ghz),” … [Read more...]
New Ceramic Disc Capacitors Save Space and Increase Reliability
Vishay Intertechnology, Inc. announced its new VYI Series of AC-line-rated ceramic disc safety capacitors. The capacitors offer reduced sizes, increased reliability and higher pulse strength up to 10 kV. The VYI Compact Series offers body diameters of 7.5 mm. “Featuring Y5U ceramic dielectrics, the VY1 Compact series is optimized for RFI and AC line filtering applications in … [Read more...]
Spaceship Antenna to Prevent Communication Blackouts
A team of scientists from the Harbin Institute of Technology proposed a new spaceship antenna to prevent space communication blackouts. The group’s research has been published in the Journal of Applied Physics. The new antenna can prevent communication blackouts in space when spacecraft are coming back into Earth’s atmosphere. “The proposed technique can maintain … [Read more...]
