Fragmentation of frequencies used for LTE, is now the main obstacle in the design of mobile devices, designed to work around the world. In total in the world for LTE frequency bands used 40, but according to the company Qualcomm, mobile solutions for the RF path, covering all ranges of LTE, while the market is missing. However, in the second half of this will change - then to begin delivery "complete system-level solutions» Qualcomm RF360, presented this week.
The structure includes Qualcomm RF360 family of chips, which will simplify the creation of mobile devices, designed to work in a variety of cellular networks. More precisely, Qualcomm RF360 supports LTE-FDD, LTE-TDD, WCDMA, EV-DO, CDMA 1x, TD-SCDMA and GSM / EDGE. The family includes the industry's first power tracker for 3G/4G LTE QFE11xx, receiver with dynamic antenna matching QFE15xx, power amplifier with built-in antenna switch QFE23xx, as well as "innovative packaging 3D-RF» QFE27xx, allow the integration of key components of the tract, including QFE23xx, in one case.
Gains from high integration inherent Qualcomm RF360, is to reduce the power consumption and the area occupied by the printed circuit board (according to the manufacturer, saves up to 50% compared to current solutions). Additional winnings, provides a complete solution, include increased flexibility and cost savings in the design.
