This switch has been designed for use where extremely high linearity, low control voltage, 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 AS190-73 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications. 0.037 (0.95 mm) REF. 0.057 (1.45 mm) 0.035 (0.90 mm) 0.006 (0.15 mm) 0.000 (0.00 mm) Description 0.071 (1.80 mm) 0.052 (1.30 mm) PIN 1 INDICATOR PIN 1 0.012 (0.30 mm) TYP. 5.0˚ ± 1˚ 0.014 (0.26 mm) 0.004 (0.10 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, +3 V) Parameter1 Insertion Frequency Loss2 Min. 0.1–0.5 GHz 0.5–1.0 GHz 1.0–2.0 GHz Isolation 0.1–0.5 GHz 0.5–1.0 GHz 1.0–2.0 GHz VSWR3 0.1–1.0 GHz 1.0–2.0 GHz 22 15 10 Typ.
