Abstract: 

High reflection load pull tuners are proposed, which include two or more RF probes, placed in series into the same slotted airline (slabline) and being controlled simultaneously horizontally and vertically by remote electric control, allowing the creation of controlled reflection factors which are distributed over and cover the entire Smith Chart, from very low reflection factors up to very high reflection factors and a method allowing to align such tuners and to calibrate such tuners on a vector network analyzer.
