Abstract:
A circuit structure may include first and second transmission lines, each with a center conductor extending along or between one or more spaced-apart conducting surfaces. A conducting surface, such as a ground, reference, or signal-return plane, of the first transmission line may have an orientation that is transverse to the orientation of a conducting surface of the second transmission line. Each of the conducting surfaces of the first transmission line may contact one or more of the conducting surfaces of the second transmission line. In some examples, one or both of the transmission lines are slablines, and in some examples, the contacting edges or edges adjacent the contacting edges of the respective conductive surfaces are curved.

Abstract:
A circuit structure may include first and second transmission lines having coupled center conductors. In the first transmission line, the center conductor may be between first and second spaced-apart extended conducting surfaces, with the space between the first and second conducting surfaces forming a cavity. An example of the first transmission line is a slabline. One or more of the second transmission lines may each be coaxial transmission lines having an outer conductor substantially surrounding the associated center conductor. The center conductor of each second transmission line may be coupled to and extend orthogonally of the center conductor of the first transmission line. In some examples, the outer conductor may extend between the center conductor of the associated second transmission line and the cavity.

Abstract:
An apparatus comprising at least two controllers and one or more links. Each controller may be configured to control one or more transmitters and one or more receivers in response to a control state signal. The one or more links may be configured to allow communication between the controllers to automatically perform characterization of the one or more links with a link packet protocol.
