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, 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-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.
The SW-442 is fabricated using a mature 0.8 micron GaAs
MESFET process. The process features full passivation for
increased performance and reliability.

1. External DC blocking capacitors are required on all RF ports and
GND. GND capacitors can be used with postive control voltage to
resonate lead inductance for improved isolation.
2. If negative control is used, DC blocking capacitors and GND
capacitors are not required.

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