Description
The SKY77769 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, IV, V, VIII into a single compact
package. The SKY77769 meets stringent spectral linearity requirements for WCDMA, HSDPA,
HSUPA, HSPA+ transmission with high power-added efficiency. 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 SKY77769 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 VENHB and VENLB 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.
