The SKY77191 Power Amplifier Module (PAM) is a fully matched 10-pad surface mount module
developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient
module packs full 1710–1785 MHz bandwidth coverage into a single compact package. Because of
high efficiencies attained throughout the entire power range, the SKY77191 delivers unsurpassed
talk-time advantages. The SKY77191 meets the stringent spectral linearity requirements of High
Speed Downlink Packet Access (HSDPA) data transmission with high power added efficiency. A
directional coupler is integrated into the module thus eliminating the need for any external coupler.
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 SKY77191 PAM is manufactured with Skyworks’ InGaP GaAs Heterojunction Bipolar Transistor
(HBT) BiFET process that provides for all positive voltage DC supply operation while maintaining high
efficiency and good linearity. Primary bias to the SKY77191 is supplied directly from any 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. No
VREF voltage is required. Power down is accomplished by setting the voltage on VENABLE 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.
