Description
M/A-COM’s SW-442 is a GaAs monolithic switch in
a low cost SOT-26 surface mount plastic package.
The SW-442 is ideally suited for applications where
very low power consumption, low insertion loss and
very small size are required.
Typical application is in dual band systems which
require switching between small signal components
such as filter banks, single band LNA's, converters
etc. The SW-442 can be used in applications up to
0.25 Watts in systems such as CDMA, W-CDMA,
PCS, DCS1800, GSM and other analog/digital
wireless communications systems.

Negative Control Voltage
The SW-442 is fabricated using a mature 0.5 micron
GaAs PHEMT process. The process features full
passivation for increased performance and
reliability.
