Description
The SKY78013 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, 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 SKY78013 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 SKY78013 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 1, 3, 5, 8, and 20;
operate at different power modes. The module is fully controllable
via four logic lines and band-enable interfaces.
LTE: The SKY78013 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 SKY78013 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 SKY78013 provides three vacant broadband TRx
ports for additional band requirements.
