AS128-73
Description
The AS128-73 is a FET IC high power SPDT switch in a
SOT-6 plastic package. This switch is designed for use
where extremely high linearity, 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
2 W. The AS128-73 switch can be used in many analog
and digital wireless communication systems including
cellular applications.
