Description
M/A-COM鈥檚 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 applica-
tions up to 0.25 Watts in systems such as CDMA, W-CDMA,
PCS, DCS1800, GSM and other analog/digital wireless commu-
nications 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.
