Description

The MASWSS0199 is an industry leading GaAs

pHEMT MMIC single pole three throw (SP3T)

CDMA-GPS switch in a lead-free 3 mm 12-lead

PQFN package.

The MASWSS0199 is uniquely configured to enable

switching from a common antenna port to CDMA

cellular, CDMA PCS, or GPS ports. The design is

asymmetric and has been fully optimized for

excellent cross modulation performance in CELL

and PCS paths while still maintaining excellent

insertion loss and isolation.

The MASWSS0199 is fabricated using a 0.5 micron

gate length GaAs pHEMT process. The process

features full passivation for performance and

reliability.
