Skyworks SKY13318-321LF is a broadband DPDT switch
designed to combine T/R and antenna diversity switching func-
tions 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.
