Abstract
Abstract An RF wave periodic delay line is disclosed having thermal energy dissipation and support structure of an insulating material with reduced ''''dielectric loading'''' between adjacent elements. For devices requiring internal attenuation to prevent undesired oscillations the appropriate attenuator structure is mounted independently of the dissipation and support structure.
