The SKY77187 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 1850–1910 MHz bandwidth coverage into a single compact package. Because of

high efficiencies attained throughout the entire power range, the SKY77187 delivers unsurpassed

talk-time advantages. The SKY77187 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 SKY77187 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 SKY77187 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.
