RFMD’s PowerSmart power platforms achieve HSPA+ 4G data upload speeds with 15% less current

RF Micro Devices Inc of Greensboro, NC, USA says that it has achieved a major performance milestone related to its PowerSmart power platforms (a new product category for future multimode, multi-band cellular RF architectures).

During independent product testing, the PowerSmart power platforms achieved HSPA+ 4G data upload speeds while drawing about 15% less current than competitive solutions, the firm says. Product qualification tests, which are routinely performed to evaluate each new cellular product’s front end, transceiver and baseband, are currently being conducted in support of a product family spanning multiple form factors, to be launched by a leading cellular device manufacturer in the March quarter.

PowerSmart power platforms feature a new RF Configurable Power Core that delivers multiband, multi-mode coverage of all cellular communications modulation schemes, including GSM/GPRS, EDGE, EDGE Evolution, CDMA, 3G (TD-SCDMA or WCDMA) and 4G (HSPA+, LTE or WiMAX). HSPA+ 4G devices are capable of maximum data upload speeds of 22Mbps. Because the RF Configurable Power Core in PowerSmart is compliant with all current and known future 4G data standards (HSPA+, LTE QPSK, LTE 16QAM, and LTE 64QAM), RFMD expects that subsequent smartphones featuring PowerSmart will support upload speeds significantly greater than 22Mbps.

In addition to the RF Configurable Power Core, which performs all power amplification and power management functionality, RFMD’s PowerSmart power platforms include all necessary switching and signal conditioning functionality in a compact reference design, providing smartphone makers a single scalable source for the entire cellular front end, says the firm.
