| HWS447 GaAs DC-6 GHz SPDT Terminated Switch August 2007 V5 Features * Low Insertion Loss : 0.50 dB @ 2.7 GHz QFN12L (3 x 3 mm) 0.60 dB @ 5.8 GHz * Isolation: 29 dB @ 2.7 GHz 22 dB @ 5.8 GHz * Low DC Power Consumption * Miniature QFN12L (3x3 mm) Plastic Lead (Pb) Free Package, RoHS Compliant * PHEMT process Description The HWS447 is a GaAs PHEMT MMIC SPDT switch operating at DC-6 GHz in a low cost miniature QFN12L (3 x 3 mm) plastic lead (Pb) free package. The HWS447 features low insertion loss and high isolation with very low DC power consumption. This switch can be used in WiMAX or IEEE 802.11a/b/g WLAN PC card and access point applications as transmit/receive switch, antenna diversity switch, or band-selection switch.
