A radio-frequency high-voltage waveguide device including an electrical conductor configured for operation with a radio frequency and a high voltage relative to a gaseous environment and/or a ground body, an electrically conductive contact unit that is in contact with the conductor at at least one point, the contact unit being arranged on an electrically insulating mount, and an electrically conductive field distribution assembly arranged on the electrically conductive contact unit, the assembly being electrically conductively connected to the contact unit and arranged at least partly in an inside of the mount.

High-frequency high-voltage waveguide device

This disclosure relates to directional couplers and methods of tuning directional couplers formed in a printed circuit board. The directional couplers include a main line for transmitting power and at least one secondary line having a coupling portion arranged parallel and at a distance from the main line in a coupling region. The directional coupler includes one or more additional coupling lines that have a coupling portion that runs parallel to and at a distance from the coupling section of the at least one secondary line. The one or more additional coupling lines have a connection arranged on the outer portion of the printed circuit board for selective grounding or connection to an external connection.

Directional couplers and methods for tuning directional couplers

One aspect of the invention includes a directional coupler having a coupling factor in the forward direction determined from the equation=C&#xb7;e, a coupling factor in the reverse direction determined from the equation=C&#xb7;e, an isolation in the forward direction determined from the equation=I&#xb7;e, and an isolation in the reverse direction determined from the equation=I&#xb7;e, wherein at least one condition is met from among the group consisting of: (1) the absolute value of &#x394;&#x3c6;=&#x3c6;+&#x3c6;&#x2212;(&#x3c6;+&#x3c6;) being less than or equal to 20&#xb0;, is less than or equal to 1.6, and (3) Cf=Cr and If=Ir.
