Description
The HWS465 is a GaAs PHEMT MMIC DPDT
switch operating at DC-6 GHz in a low cost
miniature QFN12L (3 x 3 mm) plastic lead (Pb) free
package. The HWS465 features low insertion loss
and high isolation up to 6 GHz 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.
