‘Emi Filtering’
An Electronicstalk guide
Start with the news release AC/DC power converters for medical applications from Bear Power Supplies, which we summarised at the time by saying "Bear's compact and rugged BP Series encapsulated AC/DC power converters are available for purchase online, simplifying OEM evaluation for commercial, industrial and medical applications. ". Several months prior to that, we featured the news release Low-power network platform for harsh environments from Axiomtek: "Axiomtek has announced the NA-320FL, a fanless 1U compact network appliance platform with 6GB LANs that supports the low-power Intel Atom processors D510 1.66GHz with Intel ICH8M PCH chipset.".
In December 2010, we covered the news from Maxim Integrated Products - take a look at VGA for wireless infrastructure transceivers which says: "Maxim Integrated Products has introduced the MAX2062, a fully programmable, multistate, dual-channel, analogue and digital IF/RF variable-gain amplifier suitable for automatic gain control circuits.".
Take a look also at the news release from Allegro Microsystems, Sensor IC withstands harsh automotive environments, as well as FPGA-based frame grabbers for image acquisition from Stemmer Imaging, and Offline switcher IC eliminates no-load waste from Power Integrations.
