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.
