A superior RF front end solution.
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.
The Problem: 4G LTE and LTE-A Band Fragmentation
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.
The Solution: Simplifying LTE-Advanced Multiband RF Complexity
Building on the success of the first generation Qualcomm RF360, which is the first global RF solution for LTE devices, the latest RF360 front-end solution is designed to handle up to three bands in carrier aggregation mode and deliver the flexibility needed for even the most complex RF band configurations required by LTE Advanced. The latest RF360 power amplifier and antenna switches support more bands, while offering higher performance and power efficiency in an industry leading footprint and the latest RF360 antenna tuner offers enhanced performance through sophisticated modem-assisted control.
The Advantage: Integration at the System Level
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 works 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.
RF360 solution integrated within Qualcomm® Gobi™ modems has helped earn 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.
QFE1100, the world’s first commercial modem-assisted envelope tracker (ET) for 4G LTE multimode devices provides dynamic supply voltage to power amplifiers that minimizes heat generation, improves battery life, and enhances transmit signal quality.
The 2nd generation QFE3100 features enhanced PA efficiency, further reduced PA power consumption and heat generation, and 30% smaller footprint as compared to previous generation envelope tracker
Chips: QFE1100, QFE3100
Antenna Matching Tuner
The world’s first dynamic and reconfigurable modem-assisted commercial antenna matching tuner for 4G LTE multimode devices. It enables sleeker smartphones and tablets. This improves signal performance and extends the frequency range and band support, without the need for increasing antenna size or number.
Chips: QFE15xx, QFE25xx
CMOS Power Amplifier and Antenna Switch
Offering manufacturers an economical way of creating sleeker, yet equally connected, mobile devices, CMOS power amplifiers and antenna switches support a wide range of radio frequencies while helping save space inside your device.
Chips: QFE23xx/QFE3320 (Integrated PA/ASM), QFE33xx/QFE10xx
