AS359-62
Description
The AS359-62 is a GaAs FET IC SPDT switch in an
SSOP-8 plastic package. The 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 AS359-62 switch can be
used in many analog and digital wireless communication
systems including cellular, GSM and DECT applications.
