This switch has been designed for use where extremely high linearity, 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 0.006 (0.15 mm) 0.000 (0.00 mm) 5.0˚ ± 1˚ 0.122 (3.10 mm) 0.106 (2.70 mm) 0.022 (0.61 mm) 0.004 (0.10 mm) diversity switching over 2 W. The AS173-73 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications.
