Description
M/A-COM鈥檚 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 铿乴ter banks in
systems such as: radio and cellular equipment, PCM, GPS,
fiber optic modules, and other battery powered radio
equipment.
The SW-259 is fabricated with a monolithic GaAs MMIC
using a mature 1-micron process. The process features full
chip passivation for increased performance and reliability.
