Description
The HWS379 is a GaAs PHEMT MMIC DP4T switch
operating at DC-6 GHz in a low cost miniature
QFN16L (4 x 4 mm) plastic package. The HWS379
combines one DPDT switch and two SPDT switches
in a single IC and 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. Two antenna ports can be
selected for antenna diversity function and four RF
ports can be arbitrary chosen for 2.5 GHz band or
5.85 GHz band as transmit/receive functions.
