ABSTRACT:
A multi level splitter device suitable for CATV distribution systems utilizes transformers with bi-multiplefilar windings as well as impedance matching transformers selectively placed and port isolation techniques to provide excellent performance throughout a very broad frequency range. The device may utilize a standard JEDEC surface mount package, for example a 84 pin PLCC package which allows isolation of each of the output port terminals intermediate grounded terminals minimizing output line to output line crosstalk. Further, output line isolation is provided by use of resistors across adjacent "split" output lines.
