This switch has been designed for use where extremely high linearity and low insertion loss are required. It is controlled with positive voltage eliminating the need for negative voltage. Some standard implementations include antenna changeover, T/R and diversity switching over 2 W.The AS150-59 switch can be used in many analog and digital wireless communication systems. 7.0 0.038 (0.95 mm) TYP. 0.030 (0.75 mm) 0.017 (0.43 mm) 0.007 (0.18 mm) 0.005 (0.12 mm) 8.0 MAX. 0.006 (0.15 mm) 0.002 (0.05 mm) 0.028 (0.70 mm) 0.016 (0.40 mm) Electrical Specifications at 25C (0, +5 V) Parameter1 Insertion Loss3 Frequency2 DC-1.0 GHz 1.0-2.0 GHz 2.0-3.0 GHz DC-1.0 GHz 1.0-2.0 GHz 2.0-3.0 GHz DC-1.0 GHz 1.0-2.0 GHz 2.0-3.0 GHz 19 18 20 Min.
