Features

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

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-437 can be used in applica-

tions 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 0.8 micron GaAs

MESFET process. The process features full passivation for

increased performance and reliability.
