Description
The SKY78114, SkyOne® Ultra 2.0 is a multimode multiband
(MMMB) Front-End Module (FEM) that supports 3G/4G, and CDMA
handsets and operates efficiently in CDMA, TD-SCDMA, WCDMA,
HSPA, and LTE modes. The FEM consists of a WCDMA blocks
operating in the middle 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.
WCDMA: The SKY78114 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, and 4, and
operates at different power modes. The module is fully
controllable via a MIPI^® serial interface.
LTE: The SKY78114 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: The SKY78114 meets spectral linearity requirements of
CDMA2000 and EVDO Release A modulation with good power-
added efficiency.
TD-SCDMA: The SKY78114 meets spectral linearity requirements
of TD-SCDMA modulation dedicated transmit output port.
Receiver Section: The SKY78114 includes integrated Duplexers,
RX SAWs, and a SP10T switch which supports simultaneous
Downlink Carrier Aggregation for additional Rx data rate and
provides 3G/4G Rx paths from antenna to LNA port of RFIC.
Carrier Aggregation (CA) requirements for noise and harmonics
are designed-in for best desense performance. Additionally, GPS
and LB/HB WiFi coexistence are designed-in for exceptional
support to maintain all radio performance including 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 desense problems
and enhance sensitivity performance. With an integrated RX
consolidated switch, it is feasible to match different RX port
mapping on different platforms.
TRx and Rx Ports: The SKY78114 provides three TRx ports.
