Description

The AS191-73 is a PHEMT GaAs FET IC high-linearity SPDT switch

in a SOT-6 plastic package. This switch has been designed for use

where extremely high linearity, low control voltage, high isolation,

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 3 W. The AS191-73

switch can be used in many analog and digital wireless communi-

cation systems including cellular, GSM and DECT applications.
