Description
The SKY77656-11 is a hybrid, multimode multiband (MMMB)
Power Amplifier Module (PAM) that supports 2.5G and 3G / 4G
handsets and operates efficiently in GSM, EGPRS, EDGE, WCDMA,
and LTE modes. The PAM consists of a GSM 800/EGSM 900 PA
block, a DCS1800/PCS1900 PA block, separate WCDMA blocks
operating in 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 SKY77656-11 uses a new compact architecture
supporting the GSM850, EGSM900, DCS1800 and PCS1900
bands. The PAM also supports 2.5G Class 12 Enhanced General
Packet Radio Service (EGPRS) multi-slot operation and EDGE
linear modulation.
WCDMA: The SKY77656-11 uses an enhanced architecture to:
support WCDMA, High-Speed Downlink Packet Access (HSDPA),
High-Speed Uplink Packet Access (HSUPA), and LTE modulations;
cover multiple bands for 3GPP, including bands 1, 2, 3, 4, 5, 8;
operate at different power modes. The module is fully controllable
via MIPI interface.
TD-SCDMA / TDD LTE: The SKY77656-11 uses an enhanced
architecture that supports TD-SCDMA bands 34/39 and TDD LTE
band 39.
LTE: The SKY77656-11 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. The SKY77656-11 supports LTE Downlink
Carrier Aggregation harmonic cases with low harmonic levels.
