GaAs SPST High Isolation Switch, +3 Volt, 0.5 - 2.0 GHz SW-399 SW-399 GaAs SPST High Isolation Switch, +3 Volt 0.5 - 2.0 GHz Features • • • • SOT-26 1 High Isolation: 43 dB up to 2 GHz Low Cost Plastic SOT-26 Package Low Insertion Loss: <1.5 dB Positive Control: +3 to +8 V XX#Y PIN 1 Description M/A-COM’s SW-399 is a GaAs monolithic switch in a low cost SOT-26 surface mount plastic package. The SW-399 is ideally suited for applications where very low power consumption (<10µA@5V), low intermodulation products, very small size and low cost are required. The SW-399 is a general purpose RF switch which can be used in systems such as cellular, PCM, GSM and other analog/digital wireless communications systems. The SW-399 is a GaAs MMIC using a mature 1-micron gate length GaAs MESFET process. The process features full chip passivation for increased performance and reliability.
