New Broadband Preamplifier Announced
Langer EMV has announced a new broadband preamplifier, model PA 306, designed to boost the signal from near field probes. The frequency range is 100 kHz to 6 GHz with gain of 30 dB and noise figure of 3 dB, typical. The PA 306 amplifies weak signals from near-field probes or antennas. The preamplifier features a low noise figure performance in combination with a high dynamic … [Read more...]
How White Hat Hackers Stole Crypto Keys from an Offline Laptop in Another Room
In recent years, "air-gapped" computers, which are disconnected from the internet so hackers can not remotely access their contents, have become a regular target for security researchers. Now, researchers from Tel Aviv University and Technion have gone a step further than past efforts, and found a way to steal data from air-gapped machines while their equipment is in another … [Read more...]
Swedish Transport Administration Leads Fight Against Mobile Interference
The International Railway Journal reports that 4G and 3G mobile networks are causing severe interference to safety-critical GSM-R radio communications. Sweden's railway sector is currently engaged in an intensive programme to combat the problem by a self-imposed deadline of July 1st. Kevin Smith, of Trafikverket, reports on the project's progress, "For mission-critical radio … [Read more...]

Hack-Proof RFID Chips
Larry Hardesty, MIT News Office, reports that MIT researchers, working together with engineers from Texas Instruments, have developed a new type of radio frequency identification (RFID) chip that is virtually impossible to hack. "If such chips were widely adopted, it could mean that an identity thief couldn’t steal your credit card number or key card information by sitting … [Read more...]
Ap Note: Design of Near Field Antenna System
National Instruments has released a short application note on how to design a near field antenna system for near field communications (NFC). MFC is a non-contact communication between wireless devices and things, such as, pay terminals or to share information between devices. Examples would include the Apple Pay and Google Pay process. The ap note describes how the antenna … [Read more...]
