Description
The SKY78042 SkyOne^® Ultra, a hybrid, 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, separate WCDMA blocks
operating in the low bands, 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 ohms 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 overmold.
GSM / EDGE: The SKY78042 new compact architecture supports the GSM850 and EGSM900 bands,
as well as 2.5G Class 12 General Packet Radio Service (GPRS) multi-slot operation and EDGE linear
modulation.
WCDMA: The SKY78042 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 8 and 26, and operates at different power modes. The module is fully
controllable via a MIPI/RFFE serial interface.
LTE: The SKY78042 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 SKY78042 integrated Duplexers, RX SAWs, and the 1P8T switch support
simultaneous Downlink Carrier Aggregation for additional Rx data rate and provide 2G/3G/4G Rx paths
from antenna to LNA port of RFIC. Carrier Aggregation (CA) requirements for noise and harmonics are
designed-in for best de-sense performance. Additionally, GPS and LB/HB WiFi coexistence are also
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 module mitigate de-sense problems and enhance sensitivity
performance.
TRx and Rx Ports: The SKY78042 provides two TRx ports.
