PRODUCT SUMMARY
SKY78027-12 SkyOne™ MULTIMODE MULTIBAND FEM for QUAD-BAND
GSM/GPRS/EDGE – WCDMA/HSPA/HSPA+/LTE/CDMA
Description
The SKY78027-12 SkyOne™ Multimode Multiband (MMMB)
Front-End Module (FEM) supports 2.5G, 3G/4G, and CDMA
handsets and operates efficiently in GSM, GPRS, EDGE, 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 high bands, duplexers for bands
1, 2, 3, 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 internally matched to 50
Ω,
minimize the need for
external components. Extremely low leakage current maximizes
handset standby time. The InGaP/GaAs die and passive
components are mounted on a multi-layer laminate substrate and
the assembly encapsulated in plastic over-mold.
Filter Integration:
Duplexers for bands 1, 2, 3, 5, and 8 are
designed into the SKY78027-12. 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.
WCDMA:
The SKY78027-12 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, 5, and 8, and
operates at different power modes. The module is fully
controllable via a MIPI serial interface.
LTE:
SKY78027-12 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.
CDMA:
SKY78027-12 meets spectral linearity requirements of
CDMA 2K and EVDO Release A modulation with good power-
added efficiency.
Receiver Section:
The integrated Duplexers, RX SAWs, and
SP16T SOI switch of the SKY78027-12 provide 2G/3G/4G Rx
paths from antenna to LNA port of RFIC. Additionally, GPS and
LB/HB WiFi coexistence are designed-in for exceptional support to
maintain all radio performance, even in user 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.
GSM/EDGE:
The SKY78027-12 with new compact architecture,
TRx and RX Ports:
The SKY78027-12 provides eight auxiliary
supports the GSM850, EGSM900, DCS1800 and PCS1900 bands,
ports.
as well as 2.5G Class 12 Enhanced General Packet Radio Service
(EGPRS) multi-slot operation and EDGE linear modulation.
