Impedance Tuners with Rotating Probes / 9,257,963

Tuesday, February 9, 2016

A new slide-screw impedance tuner structure uses eccentrically rotating metallic probes. This
ensures high resolution in the area where the gap between center conductor and probe is small
(high GAMMA), a smooth increase of proximity between probe and center conductor (basic
anti-corona form) and the possibility to compensate for the negative phase slope at higher
GAMMA, native to traditional slide screw tuners. Additionally the new structure simplifies the
tuner mechanics by eliminating the need for a precise vertical axis
