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.
