Skyworks Solutions Inc of Woburn, MA, USA (which manufactures analog and mixed-signal semiconductors) says that a family of diversity receive modules (DRx) for LTE smartphones is currently ramping with several tier-one manufacturers. The firm says that the new product category leverages its systems-level expertise and techniques developed for cellular base-stations to create a solution integrating multiple low-loss RF switches, receive SAW (surface acoustic wave) filters and low-noise amplifiers (LNAs) to dramatically enhance downlink data rates in LTE advanced MIMO systems. By amplifying the receive signal without increasing noise, receiver sensitivity is improved, depending on the band. As a result, carriers benefit from improved network efficiency while consumers experience considerably faster download speeds, says Skyworks.
“Our new diversity receive modules create a performance differentiator for LTE applications and demonstrate Skyworks' device and systems level expertise, expanding product portfolio and integration capabilities,” says David Stasey, VP & general manager of analog solutions. “Further, we continue to capitalize on the need for highly specialized solutions that are driving significantly higher addressable content opportunities.”
About 75% of network traffic on mobile devices is on the downlink or receive side. Skyworks says that its highly integrated DRx modules maximize data throughput, minimize complexity and reduce overall footprint, helping mobile communication networks to deliver increasing amounts of data.
The new diversity receive solutions are now available for both sampling and production.
