PIN 1 INDICATOR 0.118 (3.00 mm) ± 0.004 (0.1 mm) SQ. 0.193 (4.90 mm) REF. ■ Low DC Power Consumption ■ Positive 3 V or 5 V Control Voltage PIN 1 7.0˚ 0.038 (0.95 mm) TYP. 0.030 (0.75 mm) Description The AS150-59 is an IC FET SPDT switch in a MSOP-8 plastic package. 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. 0.012 (0.30 mm) 0.017 (0.43 mm) + 0.006 (0.15 mm) - 0.002 (0.05 mm) 0.007 (0.18 mm) ± 0.005 (0.12 mm) 0.006 (0.15 mm) 0.002 (0.05 mm) 8.0˚ MAX. 0.028 (0.70 mm) 0.016 (0.40 mm) Electrical Specifications at 25°C (0, +5 V) Parameter1 Frequency2 Insertion Loss3 DC–1.0 GHz 1.0–2.0 GHz 2.0–3.0 GHz Isolation DC–1.0 GHz 1.0–2.0 GHz 2.0–3.0 GHz VSWR4 DC–1.0 GHz 1.0–2.0 GHz 2.0–3.0 GHz Min. 19 18 20 Typ.
