| HWS408 GaAs DC-3 GHz SPDT Switch November 2006 V5 Features * Low Insertion Loss: 0.4 dB @ 2.5 GHz * Isolation: 25 dB @ 2.5 GHz * Low DC Power Consumption * Low Cost SOT-363 Plastic Lead (Pb) Free SOT-363 Package * Lead Free and RoHS (Restrict of Hazardous Substances) Compliant Version of HWS314 Description The HWS408 is a GaAs SPDT switch operating at DC-3 GHz in a low cost SOT-363 plastic lead (Pb) free package. The HWS408 features low insertion loss with very low DC power consumption. This switch can be used in many wireless digital communication systems like IEEE 802.11b/g WLAN and Bluetooth for transmit/receive selection or antenna diversity function.
