Description
The AS218-321 is a broadband transfer 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 and 5 GHz bands.
