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.

Handling Procedures

Please observe the following precautions to avoid

damage:

Static Sensitivity

Gallium Arsenide Integrated Circuits are sensitive

to electrostatic discharge (ESD) and can be dam-

aged by static electricity. Proper ESD control tech-

niques should be used when handling these de-

vices.
