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 - 24 Jan, 2013 - Comments: 0

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

Return Of The Femtocell
By Cheryl Ajluni - 19 Nov, 2009 - Comments: 0

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
