GaAs IC High Linearity Positive Control SPDT Switch DC–2.5 GHz AS158-59 Features ■ High Linearity (55 dBm IP3 @ 1.9 GHz) MSOP-8 ■ High Isolation (28 dB @ 1.9 GHz) ■ Complementary Control Voltages (0/+5 V) 0.0256 (0.65 mm) TYP. PIN 1 INDICATOR ■ Low DC Power Consumption ■ Small Low Cost MSOP-8 Plastic Package Description The AS158-59 is an IC FET SPDT switch in a low cost MSOP-8 plastic package. The AS158-59 features extremely high linearity, low insertion loss and positive voltage operation with very low DC power consumption. Some standard implementations include antenna changeover, T/R and diversity switching over 2 W. The AS158-59 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications.
