Description
The HWS436 is a GaAs PHEMT MMIC DPDT
switch operating at DC-6 GHz in a low cost
miniature QFN12L (3 x 3 mm) plastic lead (Pb) free
package. The HWS436 features low insertion loss
and
high
isolation
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.
