Description
The HWS382 is a GaAs PHEMT MMIC SPDT
switch operating at DC-6 GHz in a low cost
miniature QFN12L (3 x 3 mm) plastic package. The
HWS382 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 PC
card
and
access
point
applications
as
transmit/receive switch, antenna diversity switch, or
band-selection switch.
