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.

A passive MMIC monopulse comparator includes a plurality of lumped element hybrids having pi and T filter structures. In one embodiment, a first hybrid receives first and second downcoverted signals and provides a first output signal to a third hybrid and second output signal to a fourth hybrid. A second hybrid receives third and fourth downconverted signals and provides respective third and fourth output signals to the third and fourth hybrids. The third hybrid provides sum and elevation channel signals and the fourth hybrid provides azimuth and G channel signals.
