Description
The AS188-92 is a PHEMT GaAs FET IC high linearity
SPDT switch in a SC-70 6 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 AS188-92 switch can be
used in many analog and digital wireless communication
systems including cellular, GSM and DECT applications.
