Time to Reevaluate RF and Microwave Power Application Development

By Dan Viza, RF and Emerging Markets Manager Freescale Semiconductor

The methods for evaluating RF power components for use in RF and microwave applications have seen relatively little change over the years in spite of the expanding universe of RF applications.

Uncertain Times for DefenseIn Defense of DARPA; Lamenting Bell Labs
By Barry Manz

A federal agency like DARPA is a sitting duck for politicians and assorted other critics. It has come up with some truly bizarre programs over years that ultimately either delivered no tangible results, were canceled before they could cause any damage, or attempted to answer questions that nobody was asking or needed answers to.
