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.
