Description

M/A-COM’s SW-259 is a GaAs MMIC SPST switch

in a low cost SOIC-8 lead surface mount plastic

package. The SW-259 is ideally suited for use where

low power consumption is required. Typical applica-

tions include transmit/receive switching, switch ma-

trices and switched filter banks in systems such as

radio and cellular equipment, PCM, GPS, fiber optic

modules, and other battery powered radio equip-

ment.

The SW-259 is fabricated using a monolithic GaAs

MMIC using a mature 1 micron process. The

process features full chip passivation for increased

performance and reliability.
