A new slide screw impedance tuner structure uses a circular slabline, eccentrically rotating disc probes and a rotating carriage allowing reducing the linear size of the tuner by a factor of 3. The slabline lies flat on the bench table surface and the disc probe rotates at the end of a rotating arm, which acts as a mobile carriage, forming a planetary configuration. The rotation of the arm controls the phase of GAMMA and the rotation of the disc-probe controls its amplitude.
