PHEMT process
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.
