www.DataSheet4U.com ADVANCE PRODUCT SUMMARY SKY77179 AutoSmart™ PA Module for WCDMA / HSDPA (824–849 MHz) Applications WCDMA handsets HSDPA handsets Description The SKY77179 AutoSmart™ Power Amplifier Module (PAM) is a fully matched, 8-pin surface mount module developed for Wideband Code Division Multiple Access (WCDMA) / High Speed Downlink Packet Access (HSDPA) applications. 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 WCDMA 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. This small and efficient module packs full coverage of the 824–849 MHz bandwidth into a single compact package. The device meets the stringent 3GPP linearity requirements up to and exceeding 28 dBm output power. 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. The SKY77179 AutoSmart™ PAM is manufactured with...
