Description
The AS190-73 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, 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 AS190-73 switch can be
used in many analog and digital wireless communication
systems including cellular, GSM and DECT applications.
