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
ultraminiature 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.
DC blocking capacitors (C
BL
) must be supplied externally.
