Description

The W3020 is a highly integrated GSM transceiver designed to operate in dual-band handsets or in single-band handsets operating at 900, 1800, and 1900 MHz frequency bands (1900 MHz performance is not verified in production). The IC architecture allows the RF designer to provide solutions for three different frequency bands with very few PCB changes, thereby providing faster time to market and reduced development time.

Features

■ 2.7 V operation, low power consumption

■ Integrated receive, transmit, and synthesizer functions

■ IF frequency and transmit offset frequency generated from the same LO

■ Integrated dual LNAs and mixers

■ Minimizes PCB design work between systems

■ Surface-mount, 64-pin TQFPT package

Applications

■ GSM dual-band hand portables:

— GSM900/1800

— GSM900/1900

■ GSM single-band hand portables:

— GSM900

— GSM1800

— GSM1900
