The globally renowned designer and manufacturer of high-performance radio frequency components and compound semiconductor technologies, RF Micro Devices, Inc., announced the commencement of volume production of multiple 3G/4G power amplifiers (PAs). The new amplifiers will support two leading smartphone families, RFMD announced.
RFMD’s portfolio comprises a range of 3G/4G solutions based on single-mode and multimode converged and hybrid architectures. This ensures compatibility with leading chipset providers and enable global platform manufacturing. Moreover, RFMD's 3G/4G solutions are claimed to reduce the thermal impact of data usage in smartphones. It also ensures increased battery life during data-based applications, such as web surfing, video calls and internet radio services.
Both of the leading smartphone brands that are supported by RFMD feature RFMD's PowerSmart power platform and RFMD's RF724x family of ultra-high efficiency power amplifiers.
RFMD's PowerSmart features a revolutionary new RF Configurable Power Core that has been designed to deliver 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).
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's RF724x UMTS/HSPA+ power amplifiers are ultra-high efficiency, single-mode 3G/4G components has been designed to deliver ultra-high peak efficiency of 48 percent-51 percent, which is significantly above current competitive offerings. The product family currently covers WCDMA bands 1, 2, 4, 5 and 8, addressing the most common UMTS/HSPA+ frequency bands and band combinations.
Both smartphone brands are manufactured by a leading North America-based smartphone manufacturer, RFMD said.
One of the smartphones based on RFMD's PowerSmart, is an all-touch handset featuring a brilliant 3.2-inch high resolution display, a 5MP camera with flash and video recording, and preinstalled social networking apps for a smoothly integrated mobile experience.
The second smartphone features RFMD's RF7241, RF7242, RF7244, RF7245, and RF7258. This smartphone features a high resolution touch display, a highly tactile keyboard, and a precise optical trackpad. The smartphone will be available in multiple triple-band 3G versions featuring RFMD's ultra-high efficiency 3G/4G PAs exclusively.
“RFMD's industry-leading 3G/4G products continue to gain design momentum with the world's leading smartphone manufacturers. Similar to calendar 2011, we believe RFMD will be a clear share gainer during calendar 2012, not only in UMTS/HSPA+, but also in 4G LTE,” president of RFMD's Cellular Products Group (CPG) claimed in a statement.
Earlier RFMD announced it has been honored with two Platinum Awards from Communications Technology magazine, a leading engineering publication in the CATV industry and the official trade journal of the Society of Cable Telecommunications Engineers (SCTE).
