Description

M/A-COM’s MASWSS0129 is a broadband GaAs

PHEMT MMIC diversity switch available in a low

cost, lead-free 3 mm 12-lead PQFN package. The

MASWSS0129 is ideally suited for applications

where very small size and low cost are required.

Typical applications are for WLAN IEEE 802.11a

and 802.11b/g systems that employ two antennas

for transmit and receive diversity. Other applications

include

cordless

phones

and

base

stations.

Designed

for

high

power,

this

DPDT

switch

maintains high linearity up to 6.0 GHz.

The MASWSS0129 is fabricated using a 0.5 micron

gate length GaAs PHEMT process.

The process

features

full

passivation

for

performance

and

reliability.
