A signal coupling system interposed between a scanning probe and a measurement instrument provides signal communication between the scanning probe and the measurement instrument. The signal coupling system has a pre-stressed shape when the scanning probe is in a neutral position. The pre-stressed shape is designated to provide a characteristic impedance of the signal coupling system that varies linearly as a function of displacement of the scanning probe from the neutral position when the scanning probe is displaced, relative to the neutral position, over a designated range of displacements.

Signal coupling system for scanning microwave microscope

A coupler assembly has first and second conductors with first and second dielectric supports extending along a coupling section and supporting the first and second conductors at a support section.

Self-supported strip line coupler

A microwave spectroscopy probe has a center conductor between a first ground plane and a second ground plane. A dielectric member has fluid channel between the center conductor and the first ground plane.

Microwave spectroscopy probe

An interconnection includes a microcircuit package having a slot, and a receiving feature. A bead ring is fitted into the receiving feature. A center conductor extends through a dielectric support disposed in the bead ring and through the slot. The center conductor forms a coaxial transmission structure in cooperation with the bead ring and the dielectric support, and forms a slab line transmission structure in cooperation with the slot.

Electrical interconnection for coaxial line to slab line structure including a bead ring

An interface to a microcircuit formed on a substrate supporting a ground plane. The substrate supports a dielectric structure having gold coated sloped sidewalls electrically connected to the ground plane. A transmission line, connected to the microcircuit, is supported by the dielectric structure. A coaxial cable is connected to the transmission line. The coaxial cable having an end stripped at an angle substantially the same as the sloped side walls of the dielectric structure, wherein the exposed length of the center conductor is bonded to the transmission line, and the outer conductor of the coax cable is bonded to the gold plating on the dielectric structure such that the angled portion of the coax cable mates with the bevel of the thick film dielectric.

Apparatus and method to introduce signals into a shielded RF circuit

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.
