SKY77601, SKY77604, SKY77605 and SKY77607 power amplifier modules

Skyworks Solutions Inc. is offering highly-integrated multimode power amplifier (PA) modules for next-generation smart phones and data cards requiring multiple W-CDMA bands. These solutions support up to five W-CDMA bands and are optimized for specific mobile data requirements.

Skyworks' devices are ideal for today's handset OEMs, smart phone providers and reference design partners, among others, who are looking to meet consumers' demand for mobile Internet applications and always-on connectivity with innovative platforms in small form factors. According to Piper Jaffray, an equity research firm, global smart phone sales alone could increase from roughly 139 million units in 2008 to 400 million units in 2011, representing a 42 percent compounded annual growth rate.

"Skyworks' new multimode and multiband power amplifier modules meet the need for increased frequency bands while reducing board space," said Gregory L. Waters, Skyworks' executive VP and general manager of front-end solutions. "Skyworks is pleased to once again be at the forefront of innovation and helping to enable tomorrow's smart phones, notebooks, netbooks, tablets, and embedded wireless devices."

The SKY77601, SKY77604, SKY77605 and SKY77607 are multimode and multiband (MMMB) PA modules for next-generation high speed packet access (HSPA) 3G phones and data modules. The devices operate efficiently in quad band GPRS and enhanced data for GSM evolution (Edge), and support bands 1, 2, 5 and 8 for W-CDMA and HSUPA modulation. The SKY77601 and SKY77604 have been designed for significantly improved performance under mismatch conditions and have reduced current consumption over the entire power range to maximize handset talk and stand-by times. In addition, to simplify the integration on the phone board the SKY77601 and SKY77604 utilize a SPI to communicate with the RF transceiver and the antenna switch module (ASM).

The SKY77602 PA module is designed for integrated data modules that support up to five W-CDMA bands1, 2, 4, 5 and 8. Skyworks' new PA module integrates the functionality of five discrete PAs into a single package, leading to significant BOM and phone board size reductions. This is the first in a family of products released throughout 2010 that are optimized for specific mobile data requirements such as fixed supply voltage, reduced output power, and significant improvements to heat dissipation.

Samples of the SKY77601, SKY77602, SKY77604, SKY77605 and SKY77607 will be available later this year.
