Skyworks Solutions has launched SkyOne Ultra 2.0, a highly integrated, single LTE SKU solution that solves harmonically-related carrier aggregation challenges through design while delivering the highest linear RF power as well as power added efficiency in the world. This next generation platform is a complete RF front-end system consisting of three LTE modules which utilize Skyworks’ revolutionary SkyBlue™ technology in addition to a separate 2G transmitter – covering all of the functionality between the transceiver output and the antenna. This innovative platform not only improves performance in terms of power output and system efficiency, it also delivers this performance in the most compact size commercially available, supporting 22 bands in less than 240 square millimeters.
With today’s high-end smartphones supporting upwards of 20 frequency bands and more than 30 carrier aggregation combinations, OEMs face tremendous challenges in managing board size and operating battery life.
SkyOne® Ultra 2.0 is a great solution as it provides excellent battery life and overall system efficiency in an industry-leading compact footprint. Further, it enables true single SKU platforms with flexible antenna support and a baseband agnostic interface, giving OEMs tremendous competitive advantages and reduced times to market.
The SkyOne® Ultra 2.0 solutions will be ramping in the first half of 2016 with several customers and consist of the following:
SKY87020-11 – a high-efficiency RF front-end power management IC for average power tracking RF power amplifier applications in portable battery powered devices. This IC includes a high-efficiency DC-DC voltage converter with a 4.5 V reference supply to provide a user-programmable RF power amplifier average power tracking supply for a 2.5 V to 5.5 V input range. The SKY87020-11 also provides an additional 4.5 V bias supply for RF power amplifier operation. This bias voltage output can supply load currents up to 3 mA and is available whenever the device is enabled. When the device is disabled, the VIN supply is bypassed to the 4V5 output.
SKY78113 – a multimode multiband front-end module (FEM) which supports 3G/4G and CDMA handsets and performs efficiently in CDMA, WCDMA, HSPA, and LTE modes. The FEM consists of a WCDMA block operating in the low bands, a logic control block for multiple power control levels, and band-enable functions in both cellular and UMTS.
SKY78114 – a multimode multiband front-end module (FEM) that supports 3G/4G, and CDMA handsets and operates efficiently in CDMA, TD-SCDMA, WCDMA, HSPA, and LTE modes. The FEM consists of a WCDMA blocks operating in the middle bands, a logic control block for multiple power control levels, and band enable functions in both cellular and UMTS.
SKY78117 – a multimode multiband front-end module (FEM) that supports 4G handsets and operates efficiently in FDD/TDD LTE modes. The FEM consists of an LTE block operating in the high bands, a logic control block for multiple power control levels.
SKY77360-12 – a power amplifier module designed for 2G quad-band cellular handsets supporting fixed gain Gaussian Minimum-Shift Keying (GMSK), fixed gain linear Enhanced Data for GSM Evolution (EDGE) modulation in the GSM850/900 and DCS1800/PCS1900 bands, and TD-SCDMA modulation in Bands 34 and 39. Class12 General Packet Radio Service (GPRS) multi-slot operation is also supported.
