ADVANCE PRODUCT SUMMARY

SKY77163 AutoSmart™ PA Module for CDMA / AMPS

(824–849 MHz)

Applications

Description

The SKY77163 AutoSmart™ Power Amplifier Module (PAM) is a fully matched, 8-pin surface mount

module developed for Code Division Multiple Access (CDMA) / Advanced Mobile Phone Service (AMPS)

and Wireless Local Loop (WLL) applications.

• Digital cellular (CDMA)

• Analog cellular (AMPS)

• Wireless local loop (WLL)

AutoSmart™ power amplifier technology internally adjusts the RF transistor bias level throughout the

dynamic operating range to minimize battery current consumption and ensure sufficient linear

performance to meet CDMA system requirements. The result is a significant savings in average

battery current without the complications of a system-supplied mode function signal or analog bias

control. AutoSmart™ response time is more than adequate for RF access probe and discontinuous

transmission operation.

Features

• Low voltage positive bias

supply

- 3.2 V to 4.2 V

This small and efficient module packs full coverage of the 824–849 MHz bandwidth into a single

compact package. The device meets the stringent IS95 CDMA linearity requirements up to and

exceeding 28 dBm output power, and can be driven to levels beyond 31 dBm for high efficiency in FM

mode operation. 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 to a 50-ohm load is realized off-chip and within the

module package to optimize efficiency and power performance.

• Low V^REF

- 2.85 V, nominal

• Low I^REF

- less than 2 mA

• Good linearity

• High efficiency

The SKY77163 AutoSmart™ PAM is manufactured with Skyworks’ 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 SKY77163 is supplied directly from a three-cell

Ni-Cd, a single-cell Li-Ion, or other suitable battery with an output in the 3.2 to 4.2 volt range. Power

down is accomplished by setting the voltage on the low current reference pin 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.

• Large dynamic range

• 8-pin package

- 3 x 3 x 1.2 mm

• Power down control

• InGaP

• IS95/CDMA2000
