Description
The SKY77705 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 880–915 MHz bandwidth coverage into a single compact package. Because of high
efficiencies attained throughout the entire power range, the SKY77705 delivers unsurpassed talk-time
advantages. The SKY77705 meets the stringent spectral linearity requirements of High Speed
Downlink Packet Access (HSDPA), High Speed Uplink Packet Access (HSUPA), and Long Term
Evolution (LTE) 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 SKY77705 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 SKY77705 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.
