Description
The SKY13252-321 is a broadband transfer switch designed to
combine T/R and antenna diversity switching functions on a
single IC. The device is designed to have a low insertion loss and
maintain high linearity at low control voltages. This low cost
switch is ideal for Wireless LAN applications and is capable of
covering both the 2.4 GHz and 5 GHz bands.
