Description

The M/A-COM MASWSS0049 is a GaAs
monolithic switch in a low cost, FQFP -N, surface
mount plastic package. The MASWSS0049 is
ideally suited for applications where very low
power consumption, high power handling, and low
cost are required. The MASWSS0049 includes an
integrated decoder and a low loss diplexer. 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 MASWSS0049 is fabricated using a new 0.5­micron 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.
