The SKY78072 (SkyOne®) from Skyworks is a hybrid, multimode, multiband (MMMB) front-end module that supports 2.5G and 3G/4G handsets and operates efficiently in GSM, GPRS, EDGE, TD-SCDMA, WCDMA, HSPA, and LTE modes. The FEM consists of a GSM800/EGSM900 PA block, a DCS1800/PCS1900 PA block, separate WCDMA blocks operating in the low and mid- bands, duplexers for bands 1, 2, 5 and 8, a logic control block for multiple power control levels, and band enable functions in both cellular and UMTS. The RF I/O ports are internally matched to 50 ohms to minimize the need for external components. Extremely low leakage current maximizes handset standby time. This highly integrated FEM solution significantly reduces time-to-market and also provides the smallest RF footprint which yields more space for form factor designers. It is available with a 56-pad configuration in a small, low profile package that measures 7 x 7.8 x 0.8 mm.
