Calibration Method for High Gamma Combo Tuner / 15/341,622

Tuesday, November 1, 2016

An RF electronic impedance tuner uses multiple PIN diodes, Varactors or MOSFETs, mounted in a low loss slab-line, between the bottom surface of the center conductor and ground, are DC controlled individually and spaced appropriately along the slab-line in order to generate maximum Gamma and bandwidth. The electronic tuner is combined with a slide screw tuner, using the same slab-line in various configurations, before, after or sharing the same slab-line section, mounted on top of each-other. Calibration on a VNA allows high Gamma and harmonic tuning.
