| HWS465 GaAs DC-6 GHz DPDT Switch September 2006 V2 Features * Low Insertion Loss : 0.8 dB @ 2.5 GHz QFN12L (3 x 3 mm) 1.0 dB @ 4.9 to 6.0 GHz * High Isolation: 37 dB @ 2.5 GHz 33 dB @ 4.9 to 6.0 GHz * Low DC Power Consumption * Miniature QFN12L (3x3 mm) Plastic Lead (Pb) Free Package, RoHS Compliant * PHEMT process Description The HWS465 is a GaAs PHEMT MMIC DPDT switch operating at DC-6 GHz in a low cost miniature QFN12L (3 x 3 mm) plastic lead (Pb) free package. The HWS465 features low insertion loss and high isolation up to 6 GHz 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.
