ABSTRACT:
A signal distribution structure, or polyline, provides isolation between signal paths in high frequency systems, such as RF or microwave communication systems. The polyline has an inner conductor surrounded by a lossy insulator and a conductive shield. The conductive shield isolates the inner conductor from high frequency signals in the system while the lossy insulator attenuates high frequency signals present on the inner conductor. Low frequency signals on the inner conductor are relatively unattenuated by the polyline. Alternatively, an open polyline is formed in which the conductive shield is absent. The polyline and the open polyline are printed on a ceramic substrate or other type of carrier using known thick-film processing techniques.
