Description
HWS419
July 2004 V1
The HWS419 is a GaAs PHEMT MMIC DP4T switch
operating at DC-6GHz in a low cost miniature QFN16L
(4 x 4 mm) plastic package. The HWS419 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 2.5GHz band or 5.85GHz band as
transmit/receive functions.
