Pasternack announces a new line of broadband logarithmic (log) video amplifiers that cover bandwidths from 0.5 GHz to 18 GHz. The amplifiers utilize GaAs semiconductor technology, which makes them ideal for use in measuring signals at high frequencies in high speed applications. “These log amplifiers can process up to 75 dB of dynamic range and have log linearity that ranges … [Read more...]
Maglev Hovering Train Breaks Speed Record
A seven car Maglev (magnetic levitation) Train in Central Japan broke its own speed record when tested near Mount Fuji this week. In 2003 the Maglev’s record was 268 mph and last week it reached 366 mph. On Tuesday the Maglev surpassed both previous records and reached 374 mph. The Maglev train hovers four inches above the tracks and is propelled by electrically-charged … [Read more...]
Invisible Objects Created in the Microwave Range Without Metamaterial Cloaking
Physicists from ITMO University, Ioffe Institute and Australian National University have made homogenous cylindrical objects entirely invisible in the microwave range without metamaterial cloaking. Until now, invisibility relied on metamaterial coatings, which can change the direction of light and make light curve around cloaked objects. However, with a new understanding of … [Read more...]
FBI Pulled Security Expert from Flight for Alleged Hacking Concerns
The FBI pulled Chris Roberts, a computer security expert, from his United Airlines Flight last Wednesday in Syracuse because of suspicions that he hacked the airplane. Roberts tweeted referencing the plane’s communication systems suggesting he was going to use his laptop to force the plane’s emergency oxygen masks to deploy. The tweet read: “Find Myself on a 737/800, let’s see … [Read more...]
Live Demo of High Power Amplifier at IMS 2015
Empower RF Systems will conduct a live demonstration of its new 1 to 3 GHz High Power Amplifier at MTT-S IMS 2015 (Booth 3226) in May, 2015. This amplifier is a 1kW amplifier in a 5U chassis. It includes an integrated dual directional coupler and instrument grade power metering. It offers different operational modes and power settings including: Automatic Gain Control (AGC) … [Read more...]
EMI Capacitors Can Withstand Extreme Humid Conditions
TDK Corporation introduces its new series of EPCOS X2 EMI suppression capacitors. These EMI capacitors are humidity resistant and can operate in temperatures up to +110 degrees Celsius. “The B3292*H/J* series for operating voltages of up to 305 V AC comprises types with rated capacitances ranging from 0.1 µF to 15 µF and lead spacings from 15 mm to 37.5 mm. In addition, the … [Read more...]
Power Inverter for Energy Grid Testing Bought by U.S. Dept. of Energy
The U.S Department of Energy’s National Renewable Energy Laboratory (NREL) has purchased its second AC/DC High Power Source from AMETEK Programmable Power. The AMETEK system is a high power inverter suited for Energy Grid Testing. If installed parallel with the previous AMETEK unit purchased in 2013, this new system can supply up to 2 MVA, which would make the system the … [Read more...]
WhiteSpace Alliance Technology Approved to Become ISO Standard
The WhiteSpace Alliance (WSA) announced its core technology, Wi-FAR, has been approved to become an ISO standard. Wi-FAR provides the industry with cost effective internet access through the TV band spectrum, also known as “whitespace,” in frequencies between 54 MHz and 862 MHz. The new standard is titled ‘ISO/IEC/IEEE Std. 8802-22:2015.’ It will improve the speed of … [Read more...]
Breakthrough in Electromagnetism to Improve Global Communication
Researchers from the University of Cambridge in England have announced an electromagnetic breakthrough – the production of an antenna so small that it can be incorporated into electronic chips. They realized electromagnetic waves are not only generated from acceleration of electronics, but also from symmetry breaking. “Symmetry breaking in physics describes a phenomenon where … [Read more...]
