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.
The SW-437 is fabricated using a mature 0.5
micron GaAs PHEMT process.
The process
features full passivation for increased performance
and reliability.
