Description

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.
