ABSTRACT:
A DC high voltage block comprising coupled lines etched upon a substrate and covered with a bubble-free, polyurethane insulating layer. The polyurethane insulating layer prevents DC voltage breakdown through air. This DC voltage block provides a planar, noncomplex circuit that can effectively provide voltage blockage up to 4500 volts. High voltage DC blocks of this nature have applications in vacuum tubes and IMPATT devices, as well as ferro-electric or electro-optic phase shifters. They are also employed to protect bias tees and electrical devices that employ bias tees.
