Description
M/A-COM’s SW-456 is a GaAs monolithic switch in a low
cost SC-70 (SOT-363) surface mount plastic package. The
SW-456 is ideally suited for applications where very low
power consumption, low insertion loss, very small size and
low cost are required. Typical application is in dual band
systems where switching between small signal components
is required such as filter banks, single-band LNA’s,
converters, etc. The SW-456 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
communication systems.
The SW-456 is fabricated using a mature 0.8 micron GaAs
MESFET process. The process features full passivation for
performance and reliability.

Handling Procedures
The following precautions should be observed to avoid
damage:
Static Sensitivity
Gallium Arsenide Integrated Circuits are ESD sensitive
and can be damaged by static electricity. Proper ESD
techniques should be used when handling these devices.

1. External DC blocking capacitors are required on all RF
ports. 1000 pF capacitors used for positive control voltage.
For higher frequency operation, smaller value DC blocking
capacitors can be substituted.
2. If negative control is used, DC blocking capacitors are not
required on RF ports.
