Description
The SKY77154 System Smart® Power Amplifier Module (PAM) is a fully matched, 8-pin surface
mount module developed for Code Division Multiple Access (CDMA) / Advanced Mobile Phone Service
(AMPS) and Wireless Local Loop (WLL) applications. This small and efficient module packs a full 824–
849 MHz bandwidth coverage into a single compact package. The device meets the stringent IS95
CDMA linearity requirements to and exceeding 28 dBm output power, and can be driven to levels
beyond 31 dBm for high efficiency in FM mode operation. A low current pin (VCONT) provides
improved efficiency for the low RF power range of 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. The output match is realized off-chip and within the module package to optimize
efficiency and power performance into a 50-ohm load. 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 SKY77154 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.
