| HWS383 ! Features * Low Insertion Loss : 0.8 dB @ 2.50 GHz * * * * ! March 2004 V2 QFN12L (3 x 3 mm) 1.0 dB @ 5.85 GHz Isolation: 29.5 dB @ 2.50 GHz 20.5 dB @ 5.85 GHz Low DC Power Consumption Miniature QFN12L (3x3 mm) Plastic Package PHEMT process Description The HWS383 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 HWS383 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.
