| HWS432 GaAs DC-6 GHz SPDT Switch September 2005 V4 Features * Low Insertion Loss : 0.4 dB @ 2.5 GHz QFN12L (3 x 3 mm) 0.5 dB @ 5.8 GHz * Isolation: 24 dB @ 2.5 GHz 27 dB @ 5.8 GHz * Low DC Power Consumption * Miniature QFN12L (3x3 mm) Plastic Lead(Pb) Free Package * PHEMT process * Lead Free and RoHS (Restrict of Hazardous Substances) Compliant Version of HWS382 Description The HWS432 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 HWS432 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 PC card and access point applications as transmit/receive switch, antenna diversity switch, or band-selection switch.
