Integrated multi-band, multi-mode power amplifier for global 3G/4G smartphones

September 24, 2012 // By Jean-Pierre Joosting
TriQuint Semiconductor has announced a multi-band, multi-mode power amplifier (MMPA) that simplifies the increasingly complex RF front-end for next-generation global 3G / 4G smartphones and other mobile devices. The compact, highly integrated TRIUMF™ MMPA achieves best-in-class power-added efficiency, providing up to 15 percent more browsing time.

The TQM7M9053 TRIUMF™ MMPA achieves best-in-class power-added efficiency (PAE) in Bands 1 and 8. The impressive 47% PAE in Band 8 translates into 15% more browsing time for users. This integrated device consumes 13 percent less PCB space than discrete components and simplifies routing to enhance system performance and time to market.

Increasing device complexity is driving demand for integrated RF solutions such as MMPAs. “Multimode, multiband PAs mark the rise of a new high-growth segment that will alter the course of the RF components industry,” said Christopher Taylor, an analyst with Strategy Analytics. He predicts that the market for MMPAs will reach more than $700 million in 2016. “The biggest opportunity for MMPAs is mid- to high-end smartphones, which use the largest number of bands and modes to ensure availability of voice and data services when roaming.”

The second-generation TRIUMF™ MMPA TQM7M9053 is drop-in, pin-compatible with the company’s highly successful TQM7M9023 MMPA, which is found in some of the most sought after smartphones and included on a leading chipset supplier’s reference design.

The versatile 5 x 7.5-mm TQM7M9053 is a fully matched MMPA that offers quad-band GSM/EDGE and WCDMA/LTE bands 1, 2, 5 and 8 to support the 3G/4G market in North America, Europe and Asia.
