Description

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

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

cost 3 mm 12-lead PQFN package. The SW-489 is

ideally suited for applications where high power, low

control voltage, low insertion loss, high isolation,

small size and low cost are required.

Typical applications are for GSM and DCS handset

systems that connect separate transmit and receive

functions to a common antenna, as well as other

handset and related applications. The SW-489 can

be used in all systems operating up to 2.5 GHz

requiring high power at low control voltage.

The SW-489 is fabricated using a 0.5 micron gate

length GaAs PHEMT process. The process features

full passivation for performance and reliability.
