PRODUCT SUMMARY

SKY77174 Power Amplifier Module for WCDMA / HSDPA

(1920–1980 MHz)

Applications

Description

• WCDMA Handsets

The SKY77174 Power Amplifier module is a fully matched 10-pad surface mount module developed

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

amplifier packs full coverage of the 1920–1980 MHz bandwidth into a single compact package. The

SKY77174 meets the stringent spectral linearity requirements of HSDPA (High Speed Downlink Packet

Access) data transmission with high power added efficiency for power output of up to 28 dBm.

Because of high efficiencies attained throughout the entire power range, the SKY77174 delivers

unsurpassed talk-time advantages.

• HSDPA Handsets

• Personal Communications

Services (PCS)

• Wireless local loop (WLL)

Features

• No VREF required

The single Gallium Arsenide (GaAs) Microwave Monolithic Integrated Circuit (MMIC) contains all active

circuitry in the module. The MMIC includes on-board bias circuitry, as well as input and interstage

matching circuits. The output match is realized off-chip within the module package to optimize

efficiency and power performance into a 50 Ω load. This device 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. Primary bias to the SKY77174 is

supplied directly from a three-cell Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output

in the 3.1 to 4.6 volt range. No V^REFvoltage is required. Power down is accomplished by setting the

voltage on V^ENABLEto zero volts. Digital bias control can be used to optimize efficiency at high and low

power or analog bias control can be used to optimize efficiency over the entire power range. No

external supply side switch is needed as typical “off” leakage is a few microamperes with full primary

voltage supplied from the battery.

• Low voltage positive bias

- 3.1 V to 4.6 V

• Supports low collector

voltage operation

• Good linearity

• High efficiency at all power

levels (17.5% at 16 dBm)

• Large dynamic range

• Low Profile package

4 mm x 4 mm x 1.1 mm

• 10-pad configuration

• Power down control

• InGaP

• Digital V^ENABLE

• Digital or Analog V^CONTROL
