GaAs 0.5-6 GHz DP4T Switch

QFN16L (4 x 4 mm)
Description
The HWS454 is a GaAs PHEMT MMIC DP4T switch
operating at 0.5-6 GHz in a low cost miniature
QFN16L (4 x 4 mm) plastic lead (Pb) free package.
The HWS454 combines one DPDT switch and two
SPDT switches in a single IC and 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 or WiMAX systems for
combination of transmit/receive and antenna diversity
functions. Two antenna ports can be selected for
antenna diversity function and four RF ports can be
arbitrary chosen for 2.5 GHz band or 5.85 GHz band
as transmit/receive functions.
