Skyworks' LTE Platform Gains Traction with 4G Handset OEMs


Showcasing its extensive line of LTE (News - Alert) product portfolio at Mobile World Congress in Barcelona, Spain, analog and mixed-signal semiconductor supplier Skyworks Solutions, Inc. said that its LTE products continue to gain traction with leading handset OEMs and smartphone makers. The products are being designed into several new and unreleased 4G devices slated for launch later this year.


According to the manufacturer, it enabled the world's first commercial LTE device, Samsung's high speed 4G USB modem, the world's first mobile LTE handset, and several platforms from ST-Ericsson (News - Alert).

Since then, Skyworks has secured additional design wins with HTC, among others, to power various 4G smartphones. According to Skyworks, 4G platforms allow consumers to access and stream data and multimedia applications anytime, anywhere at higher data rates than previous generation networks. The company said that its family of LTE products provide the most complete and flexible set of options for manufacturers developing and building 4G-enabled handsets, base stations, wireless PC cards and a host of other embedded solutions.

 “Skyworks is delighted to be an industry leader in delivering solutions that ultimately offer consumers the best user experience, particularly in this age of always on connectivity,” said Gene A. Tkachenko, senior director of engineering at Skyworks, in a statement.

He added, “By improving efficiency and performance, boosting network throughput, and simplifying roaming, Skyworks’ broad product portfolio is offering tangible benefits to handset OEMs and smartphone providers, as well as infrastructure suppliers and operators worldwide to ensure consumers have access to high-speed mobile broadband data and global coverage.”

According to the Global Semiconductor Alliance (GSA (News - Alert)), 180 operators are investing in LTE in 70 countries – with 17 networks already launched worldwide.

Skyworks’ LTE solutions include the SKY77702, SKY77703, SKY77704, SKY77706, SKY77707, SKY77708 and SKY77449. While SKY77702 is a fully matched 10-pad power amplifier module (PAM) for wideband code division multiple access (WCDMA) applications with 1850-1910 MHz bandwidth, the SKY77703 is a fully matched 10-pad PAM for WCDMA with 1710-1785 bandwidth. Both, the PAMs meets the stringent spectral linearity requirements of HSDPA, HSUPA and LTE data transmission with high power added efficiency. A directional coupler is integrated into the module thus eliminating the need for any external coupler. And high efficiencies attained throughout the power range deliver unsurpassed talk time, said Skyworks. And fully matched surface mount SKY77704 is tailored for 824-848 MHz bandwidth.

Similarly, SKY77706/07/08 are fully matched surface mount PAMs developed for LTE/evolved universal mobile telecommunications system terrestrial radio access network (EUTRAN) applications. While SKY77706 is designed to cover LTE FDD band VII, SKY77707 provides coverage of LTE bands XII/XVII bands. And SKY77708 handles LTE bands XIII/XIV. The PAM meets the stringent spectral linearity requirements of LTE modulation with QPSK/16 QAM modulations from 1.4 to 20 MHz bandwidth and full or partial resource block allocations with high power added efficiency.

Likewise, SKY77449 is a fully matched, surface mount PAM module for LTE/ EUTRAN applications, covering bands XIII, XIV LTE, EUTRAN and WCDMA from a single compact package. It also meets the stringent spectral linearity requirements of LTE modulation with QPSK/16 QAM.
