Description
The AS217-000 is a PHEMT GaAs FET IC high linearity
SPDT switch. This switch has been designed for use
where extremely high linearity, low control voltage, high
R_X isolation and low T_X insertion loss. 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 AS217-000 switch can be used in many analog
and digital wireless communication systems including
cellular, GSM and DECT applications.
