Augmented Reality and the Internet of Things

James Colby, Manager of Business Development, Littelfuse, Inc.

For those of us who wear glasses for vision correction, we are used to seeing the world through lenses. However, new technologies will allow a virtual world to be laid on top of the real world that we normally see. In other words, the lenses will become displays that allow us to see the “real” world th

A Plug 'n Play Linearizer for Your 5G RF Power Amplifier

Thomas Maudoux & Michael Jackson, Maxim Integrated

‘Mar’s Law’ presents a tongue-in-cheek perspective on how data measurements can sometimes be manipulated to fit a more linear profile than is the reality. However, there are no such shortcuts to achieving high linearity for a power amplifier (PA), which is at the heart of mobile cellular communication in
