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.
