| GaAs DPDT Switch DC - 2 GHz Features q q q q q q q q SW-289 V 2.00 SO-14 Very Low Power Consumption: 100 W Low Insertion Loss: 0.5 dB High Isolation: 25 dB up to 2 GHz Very High Intercept Point: 48 dBm IP3 Nanosecond Switching Speed Temperature Range: -40C to +85C Low Cost SOIC14 Plastic Package Tape and Reel Packaging Available1 Description M/A-COM's SW-289 is a GaAs MMIC DPDT switch in a low cost SOIC 14-lead surface mount plastic package. The SW-289 is ideally suited for use where very low power consumption is required. Typical applications include transmit/receive switching, switch matrices, digital step attenuators, and filter banks in systems such as: radio and cellular equipment, PCM, GPS, fiber optic modules, and other battery powered radio equipment. The SW-289 is fabricated with a monolithic GaAs MMIC using a mature 1-micron process. The process features full chip passivation for increased performance and reliability.
