| HWS388 ! Features * Four Inputs, Two Outputs switch * Insertion Loss: 5.5 dB * Isolation: 30.5 dB * Low DC Power Consumption * Small TSSOP16 Plastic Package * PHEMT process ! March 2004 V2 TSSOP-16 Description The HWS388 is a GaAs PHEMT 4x2 switch operating at 0.95 to 2.15 GHz in a low cost TSSOP16 plastic package. Any of the four inputs can be directed to any of the two outputs. The HWS388 is suitable for use in Direct Broadcast Satellite (DBS) switching system applications.
