How Will 5G Work?


Sumit Tomar, general manager of the Wireless Infrastructure Products Group at RF chip giant Qorvo, sat down with Semiconductor Engineering to discuss the development of next-generation 5G wireless networks and other topics. In 2014, RF Micro Devices and TriQuint merged to form Qorvo. What follows are excerpts of that conversation. SE: 5G, the follow-on to the current wireless standard known ... » read more

The Week In Review: Sept. 3


By Mark LaPedus The cellular chip supplier landscape is littered with corpses. So will 4G lead to the destruction of Qualcomm and Intel? That’s highly unlikely, according to a blog from Strategy Analytics. “With the recent announcement of a multimode LTE chipset from Intel, it seems likely that Qualcomm and Intel will maintain their status as the top two cellular radio chipset suppliers in... » read more

CMOS And SOI Invade RF Front End


By Mark LaPedus The next-generation 4G wireless standard known as long-term evolution (LTE) presents some new and difficult design choices for OEMs. One of the more difficult choices involves the less glamorous, but arguably the most critical part in a handset—the radio-frequency (RF) front-end. Typically, the RF front-end often comes in a module and includes various key components, such ... » read more

Smartphones Dial Up New RF Processes


By Mark LaPedus The rapid shift towards smartphones and tablets is driving the need for new and low-power chips at finer geometries. Today, the latest application processors, integrated basebands and other digital cell-phone chips are 28nm planar devices. And it won’t be long before OEMs incorporate 20nm planar and finFET devices in their systems as a means to reduce power and extend batt... » read more

4G Power Hog?


By Cary Chin After some frustrating inconsistencies in measuring energy efficiency of the new iPad in 3G and 4G LTE modes last month, I decided to start over and take a complete set of data. Although it takes a long time, sometimes it just makes sense to start again. The data I took this month isn’t completely consistent with my past measurements, but it feels like whatever is causing the in... » read more

Return Of The Femtocell


By Cheryl Ajluni Nothing has been left unscathed in the current global economic downturn, and that includes femtocell deployments. It was just last year that femtocells were being proclaimed a 2009 “killer app,” along with LTE and WiMAX. But what was once viewed as the next great thing has instead faced a tough road with more than a few large-scale deployments by major mobile operators be... » read more
