GaAs SPST Switch DC - 2.5 GHz SW-259 V3.00 SO-8 Features ● ● ● ● ● ● ● Very Low Power Consumption: 50 µW Low Insertion Loss: 1.0 dB High Isolation: 35 dB up to 2 GHz Very High Intercept Point: 46 dBm IP 3 Nanosecond Switching Speed Temperature Range: -40˚C to + 85˚C Tape and Reel Packaging Available 1 PIN 8 .1497-.1574 (3.80-4.00) -B- Orientation mark PIN 1 .1890-.1968 (4.80-5.00) -A.004 (0.10) 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 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. .0532-.0688 (1.35-1.75) 0°-8° -C.0040-.0098 (0.10-0.25) .013-.020 TYP.
