The SW-394 is ideally suited for use where low power consumption and high isolation are required. Typical applications include transmit/ receive switching, switch matrices and switched filter banks in systems such as radio and cellular equipment. The SW-394 is fabricated using a mature 1-micron gate length GaAs MESFET process. The process features full chip passivation for increased performance and reliability.
