| HWS400 ! Features * * High Isolation: 55 dB @ 870 MHz * 50 or 75 Ohm Systems * Low DC Power Consumption * Miniature QFN12L (3x3 mm) Plastic Package ! April 2004 V2 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.
