Description
M/A-COM’s MASWSS0166 is a GaAs monolithic
switch in a lead-free SOT-363 surface mount plastic
package. The MASWSS0166 is ideally suited for
applications where very low power consumption, low
insertion loss, very small size and low cost are
required.
Typical applications are dual band systems that
require switching between small signal components
such as filter banks, single band LNA’s and
converters. The MASWSS0166 can be used in
applications up to 0.25 Watts in systems such as
cellular, PCS, DCS1800, GSM, CDMA, W-CDMA
and other analog/digital wireless communications
systems.
The MASWSS0166 is fabricated using a mature 0.5
micron GaAs PHEMT process. The process
features full passivation for increased 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.

4. Differential voltage, V(state 1) - V(state 0), must be
+2.5 V minimum and must not exceed 8 V.
