Description
M/A-COM’s SW-259 is a GaAs MMIC SPST terminated switch
in a low cost SOIC 8-lead surface mount plastic package.
The SW-259 is ideally suited for use where very low power
consumption is required. Typical applications include trans-
mit/receive switching, switch matrices, and filter banks in
systems such as: radio and cellular equipment, PCM, GPS,
fiber optic modules, and other battery powered radio
equipment.
