Wholly owned Qualcomm Incorporated subsidiary, Qualcomm Technologies, recently introduced a new comprehensive, system-level solution meant to address cellular radio frequency band fragmentation while enabling a single global 4G LTE design for mobile devices. Indeed, the Qualcomm RF360 Front End Solution combats band fragmentation as part of a family of chips that helps OEMs more easily develop multiband, multimode devices while improving RF performance.
The RF front end solution also features the industry's first envelope power tracker for 3G/4G LTE devices, a dynamic antenna matching tuner, an integrated power amplifier-antenna switch and a 3D-RF packaging solution that incorporates key front end components.
Designed to work seamlessly, the RF360 reduces power consumption and improves radio performance in an RF front end footprint up to 50 percent smaller than most current generation devices. At the same time, this solution boasts reduced design complexity and reduced development costs, enabling faster and more efficient multimode LTE product development.
"The wide range of radio frequencies used to implement 2G, 3G and 4G LTE networks globally presents an ongoing challenge for mobile device designers. Where 2G and 3G technologies each have been implemented on four to five different RF bands globally, the inclusion of LTE brings the total number of cellular bands to approximately 40," said Alex Katouzian, senior vice president of product management at Qualcomm Technologies, in a statement. "Our new RF devices are tightly integrated and will allow us the flexibility and scalability to supply OEMs of all types, from those requiring only a region-specific LTE solution, to those needing LTE global roaming support."
Earlier in the year, Qualcomm Technologies introduced two new mobile processors: the Snapdragon 800 and 600. Representing the next generation of Qualcomm mobile processors, the Snapdragon 800 is capable of delivering vastly improved performance over the previous generation Snapdragon S4 Pro processor, while the 600 offers an improved experience for mid-level devices.
Recently, Qualcomm teamed up with Orange and Ericsson to complete the world's first live demonstration of supplemental downlink technology on L-band frequencies.
