GaAs IC High Linearity Positive Control
SPDT Switch DC–2.5 GHz
Features
■ High Linearity (55 dBm IP3 @ 1.9 GHz)
■ High Isolation (28 dB @ 1.9 GHz)
■ Complementary Control Voltages (0/+5 V)
■ 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.
