Description
The AS150-59 is an IC FET SPDT switch in a MSOP-8
plastic package. This switch has been designed for use
where extremely high linearity and low insertion loss are
required. It is controlled with positive voltage eliminating the
need for negative voltage. Some standard implementations
include antenna changeover, T/R and diversity switching
over 2 W.The AS150-59 switch can be used in many analog
and digital wireless communication systems.
