Description
The SKY77648 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 SKY77648 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 SKY77648 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 SKY77648 uses an enhanced
architecture that supports TD-SCDMA bands 34/39 and TDD LTE
band 39.
LTE: The SKY77648 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.
