Description
The SKY78011-21 SkyOne™ is a hybrid, multimode, multiband
Front-End Module (FEM) that supports 2.5G and 3G / 4G 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, 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 Ω to minimize
the number of 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 overmold.
GSM / EDGE: The SKY78011-21 uses a new compact
architecture supporting the GSM850, EGSM900, DCS1800 and
PCS1900 bands. The FEM also supports 2.5G Class 12 Enhanced
General Packet Radio Service (EGPRS) multi-slot operation and
EDGE linear modulation.
WCDMA: The SKY78011-21 uses an enhanced architecture to:
support WCDMA/High-Speed Downlink Packet Access (HSDPA)
and High-Speed Uplink Packet Access (HSUPA) modulations;
cover multiple bands for 3GPP, including bands I, II, III, V, and VIII;
operate at different power modes. The module is fully controllable
via four logic lines and band-enable interfaces.
LTE: The SKY78011-21 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.
Receiver Section: The SKY78011-21 has integrated Duplexers,
RX SAWs and SP12T SOI switch to provide 2G / 3G / 4G Rx paths
from antenna to LNA port of RFIC. Optimized “Rx paths and
matching circuits” with well-grounded guard trace (high Tx–Rx
isolation) inside module mitigate de-sense problem and enhance
sensitivity performance.
TRx Port: The SKY78011-21 provides three vacant broadband
TRx ports for additional band requirements.
