Applications
•
WCDMA handsets
Description
The SKY77460 Load-Insensitive Power Amplifier (LIPA
®
) module 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 1710–1755 MHz bandwidth coverage into a single compact
package. Because of high efficiencies attained throughout the entire power range, the SKY77460
delivers unsurpassed talk-time advantages. The SKY77460 meets the stringent spectral linearity
requirements of High Speed Downlink Packet Access (HSDPA) data 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 SKY77460 operates as a load-insensitive power amplifier providing high linearity in the presence
of high RF mismatch up to 3:1 VSWR. The module 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 VEN pad 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.
