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.
