Qualcomm RF360 Chip Set to Move You Towards a 4G Phone Era

February 23, 2013, By Sanjeev Ramachandran

Everyone knows that a 4G network now has area-wise restrictions that limit its potential considerably. Once the handset is moved out of a particular region, the network downgrades to 3G or 2G according to the network’s availability.

But to eradicate this crisis once and for all, Qualcomm has been working hard and they have indeed come up with an initial product chip. Called the RF360,  this chip counter acts for the cellular radio frequency band fragmentation and enables for the first time a single, global 4G LTE design for mobile devices.

This chip has the world’s first modem-assisted and configurable antenna-matching technology that extends antenna range to operate over 2G/3G/4G LTE frequency bands, from 700-2700 MHz. This, in conjunction with modem control and sensor input, dynamically improves the antenna’s performance and connection reliability.

This chip is designed to reduce overall thermal footprint and RF power consumption by up to 30 percent, depending on the mode of operation. By reducing power and heat dissipation, it enables OEMs to design thinner smartphones with longer battery life.

The RF360 also features an integrated CMOS power amplifier (PA) and antenna switch with multi-band support across 2G, 3G and 4G LTE cellular modes. This innovative solution provides unprecedented functionality in a single component, with smaller PCB area, simplified routing and one of the smallest PA/antenna switch footprints in the industry.

The first 3D RF packaging solution, integrates the QFE23xx multimode, multiband power amplifier and antenna switch, with all the associated SAW filters and duplexers in a single package.

Designed to be easily interchangeable, the QFE27xx allows OEMs to change the substrate configuration to support global and/or region-specific frequency band combinations. The QFE27xx RF POP enables a highly integrated multiband, multimode, single-package RF front end solution that is truly global.
