The SKY77162 System Smart
mount module developed for Code Division Multiple Access (CDMA), Advanced Mobile Phone Service
(AMPS) and Wireless Local Loop (WLL) applications in the 824–849 MHz bandwidth. This small and
efficient module packs full bandwidth coverage into a single compact package.
The SKY77162 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 pad (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 SKY77162 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 pad 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.
