Abstract: 

Multi-segment RF probes for automatic slide screw impedance tuners include a multitude of slugs, which are individually adjustable towards the center conductor of the slabline and spaced against each-other in order to create the required capacitance and transmission line space values needed for synthesizing resonant networks to match arbitrary reflection factor patterns over a given frequency range. The multi-segment probes are optimized using network synthesis software within the limits of the capacitance and inductance values allowed by the hardware. The probes allow constant phase testing for 100MHz bandwidths or more.
