Description
The AS358-62 is a GaAs FET IC high linearity SPDT
switch in an SSOP-8 plastic package. This switch has
been designed for use where extremely high linearity and
low insertion loss 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 AS358 switch can be used in many analog and digital
wireless communication systems including cellular, GSM
and DECT applications.
