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.

The MASWSS0144 is fabricated using a 0.5 micron

gate length GaAs PHEMT process. The process

features full passivation for performance and

reliability.
