General Information and Available Models

Applications and Benefits


The MT97x and MT98x series automated tuners (also known as automated impedance tuners and automated load pull tuners) are precision instruments that are optimized for a broad class of in-fixture and on-wafer applications, and may be used in any automated or manual application requiring the ability to match the impedance of a microwave circuit element or to establish specific impedances at a terminal interface. The tuner design is based on the slide screw concept using the inherently broadband slab-line transmission structure. Each unit has two non-contacting probes deliver high VSWR with superb accuracy and reliability over a wide frequency range. These probes can be fully retracted leaving a low-loss, well-matched transmission line, which is a significant benefit in power related applications where two-port tuners capable of handling large amounts of power are required. As integral components of Maury Device Characterization Solutions, these PC-based tuners are controlled using Maury's family of Device Characterization Software tools, including MT930 IVCAD, MT993 ATS and the DLL-based measurement automation environment.

Maury Microwave automed impedance tuners are ideal for load pull, harmonic load pull, active load pull, hybrid active load pull, noise figure, noise parameters and all automated tuner applications.
