A movable support for a coaxial structure, such as a coaxial feed-through, connector, or cable, allows adjusting the height of a center pin of the coaxial structure relative to the surface of a high-frequency planar microcircuit mounted on a base. The height of the center pin is optimized to provide a high-frequency transition between the coaxial transmission structure and a planar transmission structure, such as a stripline structure, on the planar microcircuit. An interference fit between the movable support and base at the operating height provides a high-quality ground contact underneath the center pin.
