Abstract
Wideband and multi-section probes (slugs) for slide-screw impedance tuners use means for mechanical limitation of vertical movement towards the center conductor of the slablines, in form of cross bar structures and/or adjustable screws or dowel pins, in order to prevent the probes from having mechanical/galvanic contact with the center conductor of the slabline. The limiting screws or dowel pins can be mounted on the probes themselves or on the vertical tuner axis. Fine adjustment allows optimizing the maximum reflection factor at various frequency ranges and probe sizes.
Claims23
A method for preventing mechanical or electrical contact between the metallic probes (slugs) and the center conductor of the slabline in slide screw impedance tuners, while allowing high reflection factor and power handling, employs adjustable mechanical stops attached either on the vertical tuner axis controlling the position of said probes or on the probes themselves;
- whereby said probes are capacitively coupled with said center conductor and can be positioned at close proximity to said center conductor.
