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.
