Skyworks launches first front-end module for 3.9G wireless

At this week’s 2008 GSMA Mobile World Congress in Barcelona, Spain, Skyworks Solutions Inc of Woburn, MA, USA is demonstrating what it claims is the industry’s first front-end module (FEM) for 3.9G wireless applications. The SKY77445 FEM is designed for long-term evolution (LTE) and evolved universal mobile telecommunication systems (UMTS) terrestrial radio access network (EUTRAN) applications. Samples are available, with volume production scheduled to begin in first-quarter 2009.

“Skyworks’ new wireless solution provides outstanding linear power performance and a high level of integration in a very compact size,” claims Dr Gene A Tkachenko, senior director of engineering responsible for LTE development. With ease-of-use and low-current dissipation, the 3.9G FEM still provides an attractive cost for handsets and mobile connectivity, he adds. The new solution uses technology including bulk acoustic wave (BAW) filters, heterostructure bipolar transistors (HBT) and advanced packaging, all developed internally and optimally integrated in the new module, Tkachenko says.

The SKY77445 Band VII (2.6GHz) high-integration LTE FEM is a fully matched, 16-pin surface-mount module. Small and efficient, it integrates the power amplifier (PA), inter-stage filter, input and output matching, power detection, and duplexer in a single 4mm x 7mm x 1.1mm package. It also provides excellent TX attenuation in the RX band, and operates at a low voltage of 3.3V with high linearity and efficiency, the firm claims. In addition, the solution meets stringent adjacent channel power radio (ACPR) and error vector magnitude (EVM) requirements, as demanded by the LTE/EUTRAN standards.
