Band II (1850–1910 MHz)

The SKY77447 Load-Insensitive Power Amplifier (LIPA

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 SKY77447

delivers unsurpassed talk-time advantages. The SKY77447 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 SKY77447 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 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.
