Skyworks DRx front-end-modules have been designed to improve receiver sensitivity and data throughput in 3G/4G multimode cellular tablets and handsets, while also reducing Rx noise figure. The FEMs are comprised of low loss RF switches, as well as receive SAW filters and low noise amplifiers.
These modules support several types of antenna configurations, including single-feed types, broadband antennas, and multi-feed antennas for carrier aggregation applications. They’re able to improve a carrier’s network efficiency by amplifying its receive signal via of the integrated LNAs. For more information on how SRx front-end-modules are able to do this, download the datasheet.
