The SKY77197 Power Amplifier Module (PAM) is a fully matched, 14-pad, surface mount module

developed for Wideband Code Division Multiple Access (WCDMA) applications. This small and efficient

module packs full WCDMA Band I and Band V coverage into a single compact package. The

SKY77197 meets the stringent spectral linearity requirements of WCDMA transmission, with high

power added efficiency for power output to 28.25 dBm (Band I and Band V). The SKY77197 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 SKY77197 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. 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.
