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: The disclosed example of an N-way RF divider has a first conductor that directs RF energy through a body to a common node of a planar conductive pattern of equiangularly spaced, radially extending arms of equal length. Secondary conductors extend orthogonally to the planar pattern through corresponding passages from the ends of the radial arms. The secondary conductors may extend parallel to and circumferentially spaced from the first conductor. Resistors may connect adjacent ends of the secondary conductors opposite from the planar conductive pattern.
