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.
