Abstract
The invention relates to a transition between stripline transmission lines that is efficient at microwave frequencies and readily fabricated, and which may be used to achieve cross-overs in stipline circuits. The transition includes a coaxial section placed between pads at the ends of the stripline conductors. The coaxial section is formed by a resilient center conductor surrounded by an incomplete circle of pins connected to the ground planes and forming the outer conductor. The connections to the pads enter the ends of the coaxial section at the azimuth of the gap in the circle of pins. Good high frequency performance despite the discontinuity between the pads and coaxial center conductor is achieved by increasing the characteristic impedance of the coaxial section and that of the stripline near the transition relative to the characteristic impedance of the stripline remote from the transition.
