PRELIMINARY DATA SHEET
Description
The SKY78071, 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 SKY78071. 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 SKY78071, 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 / HSPA / HSPA+ / LTE / TD-SCDMA
WCDMA: The SKY78071 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 SKY78071 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 SKY78071 meets spectral linearity requirements
of TD-SCDMA modulation with good power-added efficiency.
Receiver Section: The SKY78071 integrated Duplexers, RX
SAWs, and 1P9T/1P9T SOI switch provide 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 SKY78071 is fully controllable
via 2 separate MIPI serial interfaces, one for the PA engine and
one for the ASM .
