Description

The HWS398 is a GaAs SPDT switch operating at

DC-6 GHz in a low cost SOT-363 plastic package.

The HWS398 features low insertion loss 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.
