Description
The HWS383 is a GaAs PHEMT MMIC DPDT
switch operating at DC-6GHz in a low cost miniature
QFN12L (3 x 3 mm) plastic package. The HWS383
features low insertion loss and high isolation with
very low DC power consumption. This switch can be
used in IEEE 802.11a/b/g WLAN systems for
combination of transmit/receive and antenna
diversity functions.
