Skyworks Unveils World`s First Commercial LTE Device
Skyworks has announced that Samsung Electronics is leveraging one of its power amplifier (PA) modules for the GT-B3710 - a high speed fourth generation (4G) USB modem that is the world's first long-term evolution (LTE)-commercialized device.
Small and efficient, the SKY77706 LTE PA module is designed for multiple handset and data card applications and allows consumers to enjoy the benefits of high-speed data services such as advanced Web TV broadcasting, online gaming and Web conferencing. Today's 4G systems offer a comprehensive solution where data and streamed multimedia can be given to users anytime, anywhere at higher data rates than previous generation networks.
"Skyworks and Samsung are pleased to develop LTE technologies for today's leading handset OEMs, infrastructure suppliers, and operators worldwide," said Gene A. Tkachenko, senior director of engineering at Skyworks. "With LTE network commitments increasing worldwide, Skyworks is once again at the forefront of enabling next-generation solutions to help boost network throughput, improve efficiency and performance, and simplify roaming to deliver the ultimate consumer experience regardless of the platform."
Samsung’s GT-B3710 can be connected to laptop computers or other portable devices via universal-serial bus (USB). It incorporates the firm’s in-house developed LTE modem chip supporting the 2.6 gigahertz (GHz) band for LTE service. Samsung's LTE solution is fully compliant with the latest 3rd Generation Partnership Project (3GPP) LTE Release 8 (Rel-8) standard.
The SKY77706 PAM is a fully matched, surface mount module developed for LTE/EUTRAN applications. This small and efficient module packs full coverage of LTE FDD Band VII into a single compact package. The device meets the stringent spectral linearity requirements of LTE modulation with QPSK/16QAM modulations from 1.4 megahertz (MHz) to 20 MHz bandwidth and full or partial resource block allocations with high power added efficiency (PAE).
The single gallium arsenide (GaAs) microwave monolithic integrated circuit (MMIC) contains all active circuitry in the module, including the PA, input, and interstage matching. The SKY77706 is manufactured using Skyworks' bipolar field effect transistor (BiFET) process which provides for all positive voltage direct current (DC) supply operation while maintaining high efficiency and good linearity.
