Description
The SKY78117 SkyOne® Ultra 2.0 is a multimode multiband
(MMMB) Front-End Module (FEM) that supports 4G handsets and
operates efficiently in FDD/TDD LTE modes. The FEM consists of
an LTE block operating in the high bands, a logic control block for
multiple power control levels. 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.
LTE: The SKY78117 meets spectral linearity requirements of LTE
modulation with QPSK/16QAM up to 40 MHz bandwidth in Bands
38, 40, and 41 including various resource block allocations, with
good power-added efficiency.
Receiver Section: The SKY78117 integrated Duplexers support
Downlink Carrier Aggregation (CA) for additional Rx data rate and
provide 4G Rx paths from antenna to LNA port of RFIC. Carrier
Aggregation requirements for noise and harmonics are designed-
in for best desense performance. 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. An integrated RX
consolidated switch provides the ability to match different RX port
mapping on different platforms.
TRx and Rx Ports: The SKY78117 provides three Tx ports and
one Antenna port (Band 7).
