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.
Claims6
A tuning element comprising at least two RF probes having a curved slotted portion in relationship with a transmission line and tighten together with a fixing device screw going through said probes that hold said probes together with longitudinal inter-spacings between said RF probes.
A tuning element comprising a top holder where a least two RF probes can be fixed at the bottom of said top holder, said RF probes having a curved slotted portion in relationship with a transmission line where at least one RF probe is moveable along said top holder and fixable compared to said top holder with screws.
A tuning element comprising a least RF two probes that are tightened together with a thin holder inserted in a slot on the top of said RF probes, said RF probes having a curved slotted portion in relationship with a transmission line where at least one RF probe is moveable along said thin top holder and fixable compared to said top holder with screws.
