Abstract: The present invention discloses a class of independent or linked facing tuning elements to be used in loadpull high gamma slide-screw tuner consisting of a radio-frequency (RF) transmission media comprising impedance tuning elements such as probes, corrugated probes, multi-section probes or single stub/double stub harmonic resonators. Multiple carriages can support multiple pairs of independent or dependent facing tuning elements. This invention, by decreasing the distances between the probes, allows the increasing of the modulus of the VSWR/Gamma. Also two dependent probes can be controlled with only two remote controls, one for the VSWR/Gamma phase control and another one for the VSWR/Gamma amplitude control.
