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.
