Tuners Waveguide Slide Screw
Features VSWR of 20:1 Correctable to 1:02 at Any Phase Easy to Use Description The Maury series 353 tuners consist of waveguide slotted sections with a movable carriages supporting micrometer driven probes which extends down into the waveguide. These tuners are valuable tools for optimizing a mismatched load and/or source for maximum power transfer, or for establishing a specific source or load termination condition for device characterization. A major advantage of slide screw tuners over other types is the ability to independently set magnitude and phase of the reflection. Although there is some interaction, reflection phase is set by the position of the probe along the waveguide, while the magnitude is set by the probe penetration depth. Probe depth of penetration is controlled by a micrometer drive with 0.001 inch resolution and a friction lock to prevent movement after adjustment. The carriage is held in constant tension to provide smooth movement and to eliminate the need for a position lock.
