Description
The MASWSS0070 is a broadband GaAs pHEMT
MMIC SPDT switch available in a low cost 3 mm 12-
lead PQFN package. The MASWSS0070 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 PC cards and access points. Other
applications include cordless phones and base
stations. Designed for high power, this SPDT switch
maintains high linearity up to 6.0 GHz.
The MASWSS0070 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
damaged by static electricity. Proper ESD control
techniques should be used when handling these
devices.
