Skyworks introduce new multimode power amplifier modules

Skyworks Solutions Inc of Woburn, MA, USA, which manufactures linear products, power amplifiers, front-end modules and radio solutions for handset and infrastructure equipment, has introduced several highly integrated multimode power amplifier modules (PAMs) for next-generation smart phones and data cards requiring multiple wideband code division multiple access (WCDMA) bands. The solutions support up to five WCDMA bands and are optimized for specific mobile data requirements, says the firm.

"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 vice president 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."

Skyworks’ SKY77601, SKY77604, SKY77605 and SKY77607 are multimode and multiband (MMMB) PAMs for next-generation high speed packet access (HSPA) 3G phones and data modules. They operate in quad band general packet radio service (GPRS) and enhanced data for GSM evolution (EDGE), and support bands 1, 2, 5 and 8 for WCDMA and high speed uplink packet access (HSUPA) modulation.
According to the firm, 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 serial peripheral interface (SPI) to communicate with the radio frequency transceiver and the antenna switch module (ASM).

The SKY77602 PAM is designed for integrated data modules that support up to five WCDMA bands - 1, 2, 4, 5 and 8. The new PAM integrates the functionality of five discrete PAs into a single package. This is the first in a family of products to be 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.
