Qualcomm® RF360™ front-end solution includes a family of chips –power amplifiers and antenna switch, antenna matching tuner, and envelope tracker - designed to address band fragmentation in LTE and LTE-Advanced carrier aggregation while improving RF performance and helping manufacturers more easily develop multiband, multimode mobile devices that can support multiple 2G, 3G, and 4G LTE standards.
Multiple versions of the same LTE device are required to accommodate the worldwide proliferation of cellular bands—40 already and counting. The problem gets even worse when you consider the different band combinations required to support LTE-Advanced carrier aggregation.
Building on the success of the first generation Qualcomm RF360, which is the first global RF solution for LTE devices, the latest Qualcomm RF360 front-end solution is designed to handle up to three bands in carrier aggregation mode and support the flexibility needed for even the most complex RF band configurations required by LTE Advanced. The latest Qualcomm RF360 power amplifier and antenna switches are designed to support more bands, while offering higher performance and power efficiency in an industry leading footprint and the latest Qualcomm RF360 antenna tuner supports enhanced performance through sophisticated modem-assisted control.
Designed to support global and regional LTE-A carrier aggregation band combinations, Qualcomm RF360 provides a comprehensive system-level RF solution including power amplifiers, antenna switches, envelope tracking, and antenna matching that are designed to work together with the modem and RF transceivers to allow manufacturers the flexibility to design thinner, battery friendly LTE and LTE-A mobile devices that deliver higher performance using less power.
The Qualcomm RF360 solution has helped earn us many honors, including Best Chipset/Processor Product at the 2013 LTE Awards in Amsterdam, the GTI innovation award in the multimode multiband product category, a device innovation award from Telecoms.com and a communications category award from IET Innovation.
QET4100, the world’s first commercially announced 40 MHz envelope tracker (ET) for 4G LTE FDD and LTE TDD, works intelligently with the LTE modem to support power-efficient connectivity for the next generation of ultra-fast 4G+ mobile devices supporting up-link carrier aggregation.
The 2nd generation QFE3100 envelope tracker is designed to deliver enhanced PA efficiency, further reduced PA power consumption and heat generation, and 30% smaller footprint as compared to the previous generation.
