Abstract
Vertical transmission line probes having alternating capacitive and inductive sections are provided. These alternating sections can be designed to provide a desired transmission line impedance (e.g., between 10 and 100 Ohms, preferably 50 Ohms). Probe flexure in operation is mainly in the inductive sections, advantageously reducing flexure stresses on the dielectrics in the capacitive sections.
