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.
