Description
The HWS541 is a GaAs PHEMT MMIC SPDT
switch operating at 2.0-6.0 GHz in a low cost
miniature LUSON6L (1.0x1.0x0.4 mm) plastic lead
(Pb) free package. The HWS541 features low
insertion loss and high isolation with very low DC
power consumption. This switch can be used in
WiMAX or IEEE 802.11a/b/g/n WLAN PC card and
access point applications as transmit/receive switch,
antenna diversity switch, or band-selection switch.
