AS144-12
Description
The AS144-12 is a GaAs IC FET SPDT switch in a
SOIC-8 plastic package. This switch has been designed
for use where extremely high linearity and low insertion
loss are required. Some standard implementations
include antenna changeover, T/R and diversity switching
over 2 watts. The AS144-12 switch can be used in many
analog and digital wireless communications systems
including cellular, GSM and DECT applications.
