www.DataSheet4U.com PRELIMINARY INFORMATION 2 V Dual-Mode WCDMA & Dual-Band GSM/DCS Switch VER 1. SW-488 Rev 1.2 0.5 – 2.0 GHz Features GSM Power Handling with +2.0 V Control Voltage Low Power Consumption. Less than 1µA current in Receive mode. Integrated Decoder. Leadless 4 x 4mm FQFP -N, 20 Pin Package. Low Insertion Loss, 0.3 dB in GSM Transmit mode. Functional Schematic WCDMA ANT1 GND GND ANT2 GND DRX GND DRXS GRX GND GND DTX Decoder Description The M/A-COM SW-488 is a GaAs monolithic switch in a low cost, FQFP-N, surface mount plastic package. The SW-488 is ideally suited for applications where very low power consumption, high power handling, and low cost are required. The SW-488 includes an integrated decoder. The switch offers GSM power handling with below +2.5V control voltage. The supply voltage VDD should be connected to the highest available voltage. The SW-488 is fabricated using a new 0.5-micron gate length GaAs pHEMT process. The process features full chip passivation for increased performance and reliability. This switch is designed for Dual Mode WCDMA/GSM/DCS handsets where the phone needs to be able to simultaneously receive a WCDMA and GSM signal.
