The SW-259 is ideally suited for use where very low power consumption is required. Typical applications include transmit/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. 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. .050(1.27) BSC. .010(0.25) M C A M B S 8- Lead SOP outline dimensions Narrow body .150 (All dimensions per JEDEC No. MS-012-AA, Issue C) Dimensions in ( ) are in mm.
