Description
The SKY77171 AutoSmart™ Power Amplifier Module (PAM) is a fully matched 10-pad surface mount
module developed for Wideband Code Division Multiple Access (WCDMA) handsets. This small and
efficient module packs full 1920–1980 MHz bandwidth coverage into a single compact package. The
SKY77171 meets the stringent spectral linearity requirements of WCDMA transmission with high
power added efficiency for power output of up to 28 dBm.
AutoSmartTM power amplifier technology internally adjusts the RF transistor bias level throughout the
dynamic operating range to minimize battery current consumption and ensure sufficient linear
performance to meet WCDMA system requirements. The result is a significant savings in average
battery current without the complications of a system-supplied mode function signal or analog bias
control. AutoSmart™ response time is more than adequate for RF access probe and discontinuous
transmission operation.
The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active
circuitry in the module. The MMIC contains on-board 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.
The SKY77171 AutoSmart™ PAM 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 SKY77171 is supplied directly from a three-cell
nickel cadmium, a single-cell lithium 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 "environmentally
friendly" packaging
that is RoHS compliant
(European Parliament
for the Restriction of
Hazardous Substances).
