Description

The AS178-73 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. Some standard implementations include antenna changeover, T/R and  diversity switching over 2 W.The AS178-73 switch can be used in many analog and digital wireless communication systems including cellular, GSM and DECT applications.
