Skyworks Solutions, Inc. SkyOne® Multimode Multiband Front-End Module for Quad-Band GSM / GPRS / EDGE / WCDMA / HSPA / HSPA+ / FDD LTE (Bands 1, 2, 3, 4, 5, 8, 12/17, 13, 20, 27, 28) / TD-SCDMA / TDD LTE (Bands 34, 39) SKY78070

Please note: this product is being discontinued and is not recommended for new designs. The SKY78070, SkyOne® is a hybrid, multimode, multiband (MMMB) Front-End Module (FEM) 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. 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. Filter Integration: Duplexers for bands 1, 2, 5, and 8 are designed into the SKY78070. This produces a highly integrated front-end solution wherein PA matching is accomplished with pre- and post- duplexer matching circuits which eliminates any required tuning outside the module. This highly integrated solution significantly reduces time-to-market and also provides the smallest RF footprint which yields more space for form factor designers. GSM / EDGE: The SKY78070, with new compact architecture, supports the GSM850, EGSM900, DCS1800 and PCS1900 bands, as well as 2.5G Class 12 Enhanced General Packet Radio Service (EGPRS) multi-slot operation and EDGE linear modulation.WCDMA: The SKY78070 enhanced architecture supports WCDMA/High-Speed Downlink Packet Access (HSDPA) and High-Speed Uplink Packet Access (HSUPA) modulations, covers multiple bands for 3GPP including bands 1, 2, 3, 4, 5, and 8, and operates at different power modes. LTE: The SKY78070 meets spectral linearity requirements of LTE modulation with QPSK/16QAM up to 20 MHz bandwidth, including various resource block allocations, with good power-added efficiency. TD-SCDMA: The SKY78070 meets spectral linearity requirements of TD-SCDMA modulation with good power-added efficiency. Receiver Section: The SKY78070 integrated Duplexers, RX SAWs, and 1P16T SOI switch provides 2G/3G/4G Rx paths from antenna to LNA port of RFIC. GPS and WiFi coexistence are designed-in for exceptional support to maintain all radio performance, even in scenarios of simultaneous use. Optimized low insertion-loss Rx paths, matching circuits, and well-grounded guard traces (high Tx–Rx isolation) inside the module mitigate de-sense problems and enhance sensitivity performance. MIPI RFFE Control Interface: The SKY78070 is fully controllable via 2 separate MIPI serial interfaces, one for the PA engine and one for the ASM.
