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.
