Manual tuners are used both in the laboratory and as system components to establish or transform impedances for a number of applications.
Maury produces several types of manual and mechanical units with various coaxial and waveguide connectors, each suited to one or more of the general applications noted above. The blue links (below) lead to detailed specifications and other information about Maury's manual tuners, and our Sales Department or your local Maury representative can also assist you in determining the right tuner type and model for your specific applications.
Slide Screw Tuners
Slide screw tuners are particularly suited to establishing impedances for device characterization, or for any other application requiring a precisely repeatable mismatch condition. This is due to the precision with which a specific matching condition can be repeated if the tuner has calibrated position indicators. These tuners also allow the reflection magnitude and phase to be set independently.
Maury produces coaxial slide screw tuners with standard matching ranges (6:1 minimum) and with wide matching ranges (10:1 - 25:1 minimum), and waveguide slide screw tuners with a matching range up to 20:1 (correctable to less than 1.02 VSWR).
Stub tuners are basic laboratory tools used for matching load impedances to provide for maximum power transfer between a generator and a load, and for introducing a mismatch into an otherwise matched system. Typical applications include power and attenuation measurements, tuned reflectometer systems and providing a DC return for single-ended mixers and detectors. Maury produces stub tuners with frequency ranges from 0.2 to 0.5 GHz (double-stub models) and 4.0 to 18.0 GHz (triple-stub models).
