ABSTRACT:
The present invention is directed to a transmission line assembly and method of propagating signals therethrough that features forming transmission lines of the assembly to provide desired filtering properties. To that end, the assembly includes a plurality of spaced-apart transmission lines placing first and second sets of active circuits in electrical communication, with a subset of the plurality of spaced apart transmission lines having dimensions to filter unwanted characteristics of signals, propagating between the first and second sets and inductively coupled between one or more of the plurality of spaced-apart transmission lines. The method performs the function of the assembly.
