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.
