Description
M/A-COM’s MASWSS0144 is an industry leading
GaAs PHEMT single pole, three throw (SP3T)
switch in a lead-free 3 mm 12-lead PQFN package.

The MASWSS0144 is uniquely configured to enable
switching from a common antenna port to Dual Band
GSM, CDMA Cellular and PCS, or GPS Receive
ports. The design is asymmetric and has dedicated
paths for each mode, which allows each path to be
optimized for the assigned mode of operation.
Pin Configuration
The MASWSS0144 is fabricated using a 0.5 micron
gate length GaAs PHEMT process. The process
features full passivation for performance and
reliability.
