  • Wide band slip ring module
    Patent number: 4139251
    Abstract: In a module which is usable in a wide band DC to UHF range, a vernier connection is employed in a slip ring and brush assembly. A source is connected to a ring by four slip ring feeds and a load is coupled to the ring by three brush leads. The unequal number of feeds and brushes reduces the standing wave reflections on the ring enabling the module to perform satisfactorily at high frequencies.
