This switch has been designed for use where extremely high linearity, low insertion loss and ultraminiature 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 2 W. The AS139-73 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications. 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) Electrical Specifications at 25°C (0, +5 V) Parameter1 Insertion Loss3 Frequency2 DC–0.5 GHz DC–1.0 GHz DC–2.0 GHz DC–0.5 GHz DC–1.0 GHz DC–2.0 GHz DC–1.0 GHz DC–2.0 GHz 20 15 8 Min.
