QFN12L (3 x 3 mm)
Description
The HWS400 is a GaAs MMIC SPDT terminated
(non-reflective) switch in a low cost QFN12L (3x3
mm) plastic package and can be used in both 50
ohm and 75 ohm systems. The HWS400 features
low insertion loss and high isolation with very low
DC
power
consumption.
Typical
applications
include CATV and basestation systems for either
SPDT or SPST functions.
