RFMD PowerSmart Power Platforms Achieve 4G Performance
RF Micro Devices (RFMD), a designer and manufacturer of high-performance radio frequency components and compound semiconductor technologies, has achieved a major performance milestone related to its PowerSmart power platforms. RFMD’s PowerSmart power platforms are a new product category reshaping the future of multimode, multi-band cellular RF architectures.
During independent product testing, the PowerSmart power platforms achieved HSPA+ 4G data upload speeds while drawing approximately 15% less current than competitive solutions. 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 highly anticipated product family spanning multiple form factors, to be launched by a leading cellular device manufacturer beginning in the March, 2011, quarter. PowerSmart power platforms feature a revolutionary new RF Configurable Power Core that delivers multiband, multi-
mode coverage of all 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 22 megabits per second (Mbps). 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 anticipates subsequent smartphones featuring PowerSmart will support upload speeds significantly greater than 22 Mbps.
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 manufacturers a single scalable source for the entire cellular front end.
BluGlass Commissions Rainbow to Process InGaN Solar Cells
BLUGLASS has commissioned the foundry services of related party Rainbow Optoelectronics Materials Shanghai to provide device fabrication and processing services for the purposes of creating a nitride solar cell prototype designed by BluGlass.
The arrangement enables BluGlass to outsource the processing of its Indium Gallium Nitride (InGaN) solar cell designs to an expert group-III nitride company without the need to invest in additional capital equipment during the research phase. BluGlass non executive director Alan Li is the general manager of Rainbow, a semiconductor device manufacturing company which provides nitride

semiconductors (primarily LED displays) to more than 25 countries. InGaN solar cells, if successful, promise to be long lasting, relatively inexpensive and importantly, the most efficient ever created. BluGlass is developing solar cell structure designs and is now seeking to develop cell prototypes as part of its Climate Ready grant.
