The SKY77758 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 coverage for WCDMA Bands I, II, V, VIII into a single compact package. The
SKY77758 meets the stringent spectral linearity requirements of WCDMA, HSDPA, HSUPA, HSPA+
transmission, with high power added efficiency to maximum power output. A directional coupler
integrated into the module eliminates 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 SKY77758 PAM is manufactured with Skyworks’ InGaP GaAs Heterojunction Bipolar Transistor
(HBT) 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 VEN_HB and VEN_LB 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.
