##X
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.

1. All dimensions are JEDEC MO-203-AB Issue A and are shown
as in/mm.
The SW-437 is fabricated using a mature 0.8 micron GaAs
MESFET process. The process features full passivation for
increased performance and reliability.
