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 RF 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 RF Front End 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® Signal Boost™ 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 RF Front End provides a comprehensive, system-level RF front-end solution. Qualcomm RF Front End 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.
Qualcomm RF Front End brings together a vast set of advanced RF front-end technologies to build a comprehensive mobile platform that is designed to support advanced features such as Gigabit LTE and LTE Advanced.
