Utilizing advanced RF design and process technology, our RF solutions complement our advanced digital modems to provide a comprehensive, high-performance mobile RF platform.
Qualcomm RF360 front-end solution includes a comprehensive family of chips—power amplifier modules, power trackers, antenna tuners, RF switches, diversity receive modules, integrated and discrete filters, multiplexers, and extractors—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, 4G and 4G+ LTE standards.
4G/4G+ LTE 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.
Simplifying LTE Advanced multiband RF complexity
The Qualcomm RF360 front-end solution is designed to support carrier aggregation with the flexibility needed for even the most complex RF band configurations required by LTE Advanced. Qualcomm RF360 power amplifier modules, front-end modules and diversity receive modules are designed to support more bands in highly integrated configurations, while offering cutting-edge performance and power efficiency. The Qualcomm® TruSignal™ antenna performance enhancement solution is engineered to support high signal performance through sophisticated modem-assisted control.
Integration at the system level
Designed to support global and regional LTE Advanced carrier aggregation band combinations, Qualcomm RF360 provides a comprehensive, system-level RF front-end solution. Qualcomm RF360 is designed to work together with the modem and RF transceiver to allow manufacturers the flexibility to design thinner, battery-friendly LTE and LTE Advanced mobile devices that deliver higher performance using less power.

Designed to support all major cellular modes—including 2G, 3G, 4G LTE and 4G+—and major cellular bands from 700-2700 MHz, Qualcomm Technologies’ RF Transceivers offer mobile device manufacturers a highly integrated multimode design that works in multiple regions around the world.
The Qualcomm Technologies' WTR5975 Gigabit LTE RF transceiver is a single-chip RF companion to the Qualcomm® Snapdragon™ X16 LTE modem, providing a collection of advanced features and comprehensive band support, including 3.5 GHz and unlicensed 5 GHz. A new digital interconnect interface between the transceiver and the modem is designed to simplify PCB layout to facilitate the implementation of the Snapdragon X16 modem's advanced features for OEMs, and to free up valuable board space that can be utilized for larger batteries or more streamlined design.
Key features of the WTR5975:
The SDR051 mmWave transceiver is the next-gen RF companion to the Qualcomm® Snapdragon™ X50 5G modem, which will provide initial support for operation in the 28 GHz mmWave band, connecting up to 800 MHz of bandwidth via 8x100 MHz carrier aggregation. Using advanced multiple input, multiple output (MIMO) techniques such as adaptive beam forming and beam tracking and antenna switch diversity, the Snapdragon X50 5G modem can extend the range of mmWave transmissions to non-line-of-sight scenarios, and support mobility.
