Description
The AS173-73 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
insertion loss and ultra miniature package size are
required. It can be controlled with positive, negative or a
combination of both voltages.
implementations include antenna changeover, T/R and
