Importance of Probe Geometry Control at THz Frequencies

New processes are allowing electrical devices to work in frequencies greater than 100 GHz, paving the way for many new applications never before possible before. Probing devices in excess of 100 GHz has always been a challenge, so accurate measurements at 500 GHz and beyond might seem like science fiction. One of the challenges is geometry control, and with such small wavelengths at these frequencies, the smallest tolerance in waveguide and transitions geometries can produce a fuzzy Smith chart. Old coax probe and air co-planar tip technologies do not offer sufficient tolerances, but new fabricated probe tip technologies can address these needs. We will take a short look into how the Infinity Probe® technology addresses geometry control.
