GaAs SPST High Isolation Terminated Switch 0.5 - 2.0 GHz Features • • • • • SW-393 V4 Functional Schematic Terminated RF Output High Isolation: 42 dB up to 2.0 GHz Single Positive Control CMOS Compatible Logic SOIC-8 Plastic Package Description M/A-COM’s SW-393 is a GaAs monolithic SPST terminated switch in a low cost SOIC 8-lead plastic package. The SW-393 is ideally suited for use where low power consumption and high isolation are required. Typical applications include PCS and GSM LO Switching, switch matrices and switched filter banks in systems such as radio and cellular equipment. The SW-393 is fabricated using a mature 1-micron gate length GaAs MESFET process. The process features full chip passivation for increased performance and reliability.
