ABSTRACT:
The present invention discloses a class of RF corrugated probes to be used in load-pull slide-screw tuner consisting of a radio-frequency (RF) or microwave slotted airline (slabline) comprising at least one RF corrugated probe controlled horizontally and vertically by remote electric control, allowing the creation of impedances which are distributed over and cover the entire Smith chart, from perfect transparency to high reflection factors. The class of RF corrugated probes disclosed in this invention includes a single RF tuning element composed of at least two RF probes fixed together with a separate probe holder.
