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.
