Description

The HWS499 is a GaAs PHEMT MMIC DPDT

switch operating at DC-4 GHz in a low cost

miniature QFN12L (3 x 3 mm) plastic lead (Pb) free

package. The HWS499 features low insertion loss

and high isolation with very low DC power

consumption. This switch can be used in WiMAX or

IEEE 802.11b/g WLAN systems for combination of

transmit/receive and antenna diversity functions.
