Description
The AS185-92 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.
implementations include antenna changeover, T/R and
diversity switching over 2 W.The AS185-92 switch can be
used in many analog and digital wireless communication
systems including cellular, GSM and DECT applications.
