(0.41 mm) x 45 CHAMFER Description The AW002R2-12 is a high power IC FET SPDT switch in a plastic SOIC-8 package. This switch has been designed for use where extremely high linearity is 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 2 W. This switch can be used in many analog and digital wireless communication systems including cellular, GSM and PCS applications. 0.197 (5.00 mm) 0.189 (4.80 mm) 0.010 (0.25 mm) 0.004 (0.10 mm) 0.158 (4.00 mm) 0.150 (3.80 mm) 0.010 (0.25 mm) 0.007 (0.17 mm) 8 MAX.
