RF Configurable Power Core from RF Micro Devices

RF Micro Devices has unveiled a power amplifier platform (chips and design solutions) called PowerSmart for the multiband mobile communications RF architectures. RFMD's PowerSmart feature new RF Configurable Power Core supporting cellular communications modulation schemes, which includes GSM/GPRS, EDGE, EDGE Evolution, CDMA, 3G (TD-SCDMA or WCDMA/HSPA+) and 4G (LTE or WiMAX).

The chips based on the PowerSmart platforms also include all necessary switching and signal conditioning functionality in a reference design, providing highend mobile-phone manufacturers a source for the range of RF front end ICs and solutions for use in mobile phones.

RFMD claims The RFIC chips/modules with PowerSmart technology occupy a footprint, which is 35% smaller than today's highest volume quad-band RF front end devices. In a real-world comparison, versus today's highest volume triple-band 3G solution using power amplifier duplexer (PAD) modules, PowerSmart reduces board space requirements by greater than 40%.


Eric Creviston, president of RFMD's Cellular Products Group (CPG), said, "RFMD's PowerSmart power platforms deliver smartphone manufacturers enhanced performance and improvements in value and solution size that are unmatched in the cellular RF industry. PowerSmart platforms process all known cellular modulations at optimum performance, with superior energy efficiency and at the industry's lowest total cost of ownership. We anticipate significant customer adoption this year as PowerSmar enables global 3G/4G penta-band implementations with product footprints that are smaller than those of triple-band solutions. With pricing below competitive penta-band WCDMA solutions and a revolutionary architecture that enables both global platform manufacturing and real-time RF configurability of individual smartphone models, PowerSmart is indeed smart power for smartphones."

PowerSmart maximize efficiency across power levels, across data rates (voice-only to LTE) and during non-ideal load conditions, also known as "antenna mismatch." Each PowerSmart platform utilizes a standardized digital interface (SDI) and is optimized to mate with leading multi-band HSPA+/EDGE/GPRS RF transceivers.
