SKY77166 Power Amplifier Module for CDMA2000
(450-460 MHz)
Applications
• Digital cellular (CDMA2000)
• Wireless Local Loop (WLL)
Features
• Low voltage positive bias
supply: 3.2 V to 4.2 V
• Good linearity
• High efficiency across wide
dynamic range
• Dual-mode operation
• 10-pad package:
4 x 4 x 1.15 mm
• Power down control
• Low power state control
• CDMA2000
Description
The SKY77166 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module
developed for Code Division Multiple Access (CDMA2000) handsets and Wireless Local Loop
applications. This small and efficient module packs full coverage of the 450–460 MHz bandwidth into
a single compact package. The SKY77166 meets the stringent CDMA2000 linearity requirements to
and exceeding 29 dBm output power.
The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active
circuitry within the module, which includes onboard bias circuitry as well as input and interstage
matching circuits. Output match into a 50-ohm load is realized off-chip within the module package to
optimize efficiency and power performance. This device is manufactured with Skyworks’ GaAs
Heterojunction Bipolar Transistor (HBT) process that provides for all positive voltage DC supply
operation while maintaining high efficiency and good linearity.
Primary bias to the SKY77166 is supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other
suitable battery with an output in the 3.2 to 4.2 volt range. Power down is accomplished by setting the
voltage on the low current reference pin to zero volts. No external supply side switch is needed as
typical “off” leakage is a few microamperes with full primary voltage supplied from the battery.
Skyworks offers lead
(Pb)-free, RoHS

Hazardous Substances)
-compliant packaging.
