Description
Skyworks AS236-321 is a broadband DPDT switch designed
to combine T/R and antenna diversity switching functions on a
single IC. The device is designed to handle high power and
maintain high linearity at low control voltages. This-low cost
switch is ideal for Wi-Fi systems and is capable of covering
both the 2.4 GHz and 5 GHz bands.
NEW Skyworks offers lead (Pb)-free, RoHS (Restriction of
Hazardous Substances)-compliant packaging.
