Description
The SKY77661-11 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 (Dual Mode): The SKY77661-11 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.
VRAMP MODE: In GMSK modes, the PA controller provides
envelope amplitude control as a function of VRAMP and reduces
sensitivity to input drive, temperature, power supply, and process
variation. Skyworks' Finger-based Integrated Power Amplifier
Control (FB-iPAQ) minimizes output power variation into
mismatch.
In EDGE modes, VRAMP voltage and MIPI-based bias settings
optimize PA linearity and efficiency.
