Skyworks unveils next-generation diversity receive modules

Skyworks Solutions Inc of Woburn, MA, USA (which manufactures analog and mixed-signal semiconductors) has launched its next-generation diversity receive modules (DRx) for LTE smartphones.

The firm says that its newest DRx modules improve receiver sensitivity and data throughput, deliver higher levels of integration in a smaller footprint, and provide the flexibility to support multiple antenna configurations. From single-feed, broadband antennas to advanced multi-feed antennas addressing carrier aggregation, the solutions allow users to select the optimal configuration for their platform requirements.

The family of DRx modules incorporate low-loss RF switches, high-performance receive filters and low-noise amplifiers (LNAs), leveraging the firm's systems-level expertise to deliver highly integrated solutions that dramatically enhance downlink data rates in LTE advanced MIMO systems. By amplifying the receive signal, receiver sensitivity and data throughput are improved, increasing network efficiency.

"Skyworks continues to push the integration and performance envelope while capturing significantly higher content per platform," says David Stasey, VP & general manager of analog solutions. "Our next-generation diversity receive models support multiple LTE bands, reduce RF complexity and enhance data throughput - all in a simple and flexible architecture," he adds. 

About 75% of network traffic on mobile devices is on the downlink or receive side. Skyworks' highly integrated DRx modules maximize LTE data throughput, helping mobile communication networks to deliver increasing amounts of data.

Skyworks' family of next-generation diversity receive modules include the following products:

• SKY13740 - an LNA diversity module for cellular mobile devices that is optimized for single-input/output, world-roaming user equipment platforms. The solution supports cellular diversity receiver functions and is compatible with 3GPP GSM, WCDMA, LTE and LTE standards for Bands 1, 3, 4, 7, 8, 20 and 26. The module is baseband-vendor-agnostic, controlled via a standard RF front-end MIPI control interface and contained in a small 5mm x 3mm x 0.8mm 23-lead surface-mount package.

• SKY13741 - an LNA diversity module for cellular mobile devices that is optimized for China-centric user equipment platforms. It supports cellular diversity receiver functions and is compatible with 3GPP GSM, WCDMA, LTE and LTE standards for Bands 1, 3, 4, 7, 39, 40 and 41. The module is baseband-vendor-agnostic, controlled via a standard RF front-end MIPI control interface and contained in a small 4mm x 3mm x 0.8mm 24-lead surface-mount package.

• SKY13744-11 - an LNA diversity module for cellular mobile devices that is optimized for platforms supporting carrier aggregation or multi-feed antenna designs. It supports cellular diversity receiver functions and is compatible with 3GPP GSM, WCDMA and LTE standards for Bands 1, 3, 4, 7, 8, 20 and 26. Separate control registers allow the user to independently control any two low-band, middle-band, and high-band RF paths. The module is baseband-vendor-agnostic, controlled via a standard RF front-end MIPI control interface and contained in a small 5mm x 3mm x 0.8mm, 29-lead surface-mount package.

For all three modules, additional RF bands can be supported through its auxiliary ports. The new diversity receive solutions are available now for both sampling and production.

Skyworks is showcasing its product portfolio in Hall 6, Booth C41 (6C41) at the GSMA Mobile World Congress (MWC2015) in Barcelona, Spain (2-5 March).
