HWS435
GaAs DC-2.5 GHz SPDT Switch
May 2011 V4
Features
SOT-363
• Low Insertion Loss: 0.5 dB @ 2.5 GHz
• Isolation: 20 dB @ 2.5 GHz
• Low DC Power Consumption
• Low Cost SOT-363 Using Lead (Pb) free
materials with RoHS compliant
Description
The HWS435 is a GaAs SPDT switch operating at
DC-2.5 GHz in a low cost SOT-363 plastic lead (Pb)
free package. The HWS435 features low insertion
loss with very low DC power consumption. This
switch can be used in IEEE 802.11b/g WLAN
systems for transmit/receive or antenna diversity
functions.
