Description
The AS205-322 is a PHEMT GaAs FET IC high linearity
SPDT switch in a MLP 2 x 1 mm 5 lead 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 AS205-322
switch can be used in many analog and digital wireless
communication systems including cellular, GSM and
DECT applications.
