February 15, 2010... Skyworks Solutions, Inc. has introduced several integrated multimode power amplifier modules (PAMs) for next-generation smart phones and data cards requiring multiple wideband code division multiple access (WCDMA) bands. The products are first in a family to be released throughout 2010. According to Skyworks the new PAMs support up to five WCDMA bands, and they are optimized for specific mobile data requirements such as fixed supply voltage, reduced output power, and improved heat dissipation.

The SKY77601, SKY77604, SKY77605 and SKY77607 are multimode and multiband (MMMB) PAMs for next-generation high speed packet access (HSPA) 3G phones and data modules. The devices reportedly operate efficiently 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. Skyworks says that the SKY77601 and SKY77604 have improved performance under mismatch conditions, and they have reduced current consumption over power range to maximize talk and stand-by times. Additionally the company notes that the SKY77601 and SKY77604 utilize a serial peripheral interface (SPI) to communicate with the radio frequency transceiver and the antenna switch module (ASM), which simplifys their phone board integration. The SKY77602 PAM is for integrated data modules that support up to five WCDMA bands – 1, 2, 4, 5 and 8. Skyworks points out that its new PAM integrates the functionality of five discrete PAs into a single package, thereby reducing bill-of-material (BOM) and phone board size. Company News Release
