Skyworks Solutions has announced that several leading OEMs and smartphone providers are leveraging the company’s highly customisable, fully optimised SkyOne front-end solution.


SkyOne solutions incorporate the SKY77619, Skyworks’ high efficiency, multimode power amplifier module already in volume production with multiple customers. What’s more, the highly flexible solution contains a common footprint that can be implemented by all of the world’s carriers and in various regions. Skyworks will be sampling third generation solutions next month and is already developing fifth generation architectures with multiple OEMs.


Sampling now, these second generation, hybrid, multimode, multiband, patented front-end modules with low insertion loss support 2.5/3G/4G handsets and operate efficiently in quad- band GSM, GPRS, EDGE, WCDMA, HSPA and LTE modes.


The ultra compact, 7 x 9.8 x 1.05 millimetre packaged FEMs consist of a GSM800/EGSM900 power amplifier block (PA), a DCS1800/PCS1900 PA block, separate WCDMA blocks operating in the low and high bands, logic control block for multiple power control levels as well as band-enable functions in cellular and universal mobile telecommunications system.


The SkyOne platform, which integrates all RF and analogue content between the transceiver and antenna, reduces complexity, size and time-to-market for customers with demanding architectures for advanced mobile applications.


Skyworks says that SkyOne is the world’s first semiconductor device to condense multiband power amplifiers and high throw switches along with all associated filtering, duplexing and control functionality into a single, ultra-compact package- -all in less than half the area of the industry’s most advanced approach.


The platform utilises Skyworks’ full technology portfolio and advanced multichip module capabilities including proprietary shielding and packaging.


At the same time, the solution is claimed to provide the world’s best linearity and power added efficiency for smart RF integration. As a result, SkyOne offers smartphone, tablet and ultrabook OEMs improved efficiency, drastically reduced RF paths, ease of implementation and a scalable platform as bands increasingly proliferate worldwide.


“Consumer demand for increasingly thinner mobile platforms with increased talk and data access time is creating unprecedented analogue and RF complexity as well as harmonic coexistence issues. Skyworks is delighted to solve this system challenge with our breakthrough SkyOne platform,” says Liam K. Griffin, executive vice president and corporate general manager at Skyworks.


“SkyOne is a proven architecture that optimises performance beyond what is possible with existing approaches and incorporates all 2G, 3G and 4G/LTE protocols enabling seamless global roaming and extended battery life. Incorporating Skyworks’ arsenal of tested and patented technologies and leveraging GaAs, SOI, SiGe and CMOS processes, SkyOne can be modulated and customised depending upon the system requirements and roadmaps of each OEM,” adds Griffin.


Radio frequency I/O ports are internally matched to minimise external components while extremely low leakage current maximizes handset standby time. The InGaP/GaAs die and passive components are mounted on a multi-layer laminate substrate and the assembly encapsulated in plastic overmold.

Anadigics adds another InGaP PA to its small-cell family


The new indium gallium phosphide based power amplifier is suited to WCDMA / LTE applications for picocells, enterprise- class femtocells, and CPE


Anadigics, a developer of radio frequency (RF) solutions, has introduced the AWB7224 small-cell power amplifier (PA).


The firm claims its AWB7224 is optimised to deliver an industry- leading combination of efficiency, linearity, output power and thermal characteristics for WCDMA, HSPA, and LTE small-cell base stations operating in the 728 to 768 MHz frequency band.


Manufacturers are able to leverage this performance to develop infrastructure solutions that consume less power, and provide higher throughput and greater coverage.


“Anadigics continues to expand its family of small-cell power amplifiers to target the 3G and 4G frequency bands most used in dense population areas,” says Glenn Eswein , director of product marketing for infrastructure products at Anadigics. “The rapid increase in wireless data consumption, especially in urban and campus settings, places tremendous pressure on existing wireless infrastructure. Our solutions enable the design of high throughput, reliable, and compact small-cell base stations that offer service providers an economical and
