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.
