This switch has been designed for use where extremely high linearity, low control voltage, high isolation, low insertion loss and ultra miniature package size are required. It can be controlled with positive, negative or a combination of both voltages. Some standard implementations include antenna changeover, T/R and diversity switching over 3 W. The 0.122 (3.10 mm) 0.106 (2.70 mm) 0.022 (0.61 mm) 0.004 (0.10 mm) AS191-73 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications.
