Features

Description

M/A-COM’s SW-489 is a GaAs PHEMT MMIC single

pole three throw (SP3T) high power switch in a low cost

miniature FQFP 12-lead 3x3mm thin profile package.

The SW-489 is ideally suited for applications where high

power, low control voltage, low insertion loss, high isola-

tion, small size and low cost are required. Typical appli-

cations are for GSM and DCS handset systems that con-

nect separate transmit and receive functions to a com-

mon antenna, as well as other handset and related appli-

cations. This part can be used in all systems operating

up to 2.5 GHz requiring high power at low control volt-

age.

The SW-489 is fabricated using a 0.5 micron gate length

GaAs PHEMT process. The process features full pas-

sivation for performance and reliability.
