DESCRIPTION
SW408 is a GaAs switch designed for 0.1 to 3GHz
frequency band application. This switch can be used
for Tx/Rx selection or antenna diversity function of
many wireless communication systems.
SW408 is housed in a low cost SOT-363 lead (Pb)
free plastic package, and features low insertion loss,
low current consumption and fast switching speed.
