Abstract
A radio frequency device comprising a signal processing means joined to electromagnectic transmission means, and latently susceptible, at the junction of the signal processing means and the electromagnetic transmission means, to adverse operating effects such as electromagnetic interference (EMI), and/or radio frequency leakage. At this junction is disposed a layer of a material which is blockingly effective against the adverse operating effects, and has a volumetric resistivity of from about 10.sup.-3 to about 2,000 ohm-centimeter. Also disclosed is a corresponding method of assembling a radio frequency device of such type. The invention has utility in application to devices such as impedance matching devices, impedance coupling devices, ground protection devices, radar transceivers, and signal splitters, a prefered application being to cable television junction boxes.
