Description
The AS193-73 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
control voltage, high isolation, low insertion loss and ultra
miniature 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 3 W. The
