Description
M/A-COM’s SW-437 is a GaAs monolithic switch in a
low cost SOT-363 surface mount plastic package.
The SW-437 is ideally suited for applications where
very low power consumption, low insertion loss, very
small size and low cost are required. Typical appli-
cation is in dual band systems where switching be-
tween small signal components is required such as
filter banks, single band LNA’s, converters etc. The
SW-437 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.
Functional Schematic
Negative Control Voltage
The SW-437 is fabricated using a mature 0.5
micron GaAs PHEMT process.
The process
features full passivation for increased performance
and reliability.

3. For positive voltage control, external DC blocking
capacitors are required on all RF ports (39 pF capacitors
are recommended).
4. If negative control is used, DC blocking capacitors are not
required on RF ports. This switch is not meant to pass or
switch a DC voltage.
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.
