| HWS407 ! Features * Low Insertion Loss : * * * * ! March 2004 V3 QFN12L (3 x 3 mm) 0.7 dB @ 2.5 GHz 0.9 dB @ 4.9 to 6.0 GHz Isolation: 25 dB @ 2.5 GHz 30 dB @ 4.9 to 6.0 GHz Low DC Power Consumption Miniature QFN12L (3x3 mm) Plastic Package PHEMT process Description The HWS407 is a GaAs PHEMT MMIC DPDT switch operating at DC-6 GHz in a low cost miniature QFN12L (3 x 3 mm) plastic package. The HWS407 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.
